1.1 Introduction to TRILLTransparent Interconnection of Lots of Links (TRILL) is a protocol that applies Layer 3 linkstate routing technologies to Layer 2 networks. TRILL extends Intermediate System toIntermediate System (IS-IS) and uses the Shortest Path First (SPF) algorithm to calculate routes.

OverviewTraditional data center operators provide basic infrastructure-based services for users. As theInternet develops constantly, services increase dramatically, users require more efficient, secure,and reliable services. At the same time, data center operators need to reduce costs and providemore value-added services. Cloud computing that provides a new service mode for data centeroperators is an effective solution. However, data centers using cloud computing require morebandwidth resources. In addition, virtual device technologies that connect data centersseamlessly and support file sharing and data copying between data centers are necessary forcapacity expansion and disaster recovery. However, virtual device relocation multiplies thedifficulty in network deployment and management. In this situation, large-scale Layer 2networks are required.TRILL extends IS-IS and combines configuration flexibility of Layer 2 networks and the largescale of Layer 3 networks. It boasts easy deployment, highly-efficient forwarding, high-speedconvergence, and loop prevention and provides a better solution to data centers.

CharacteristicsCompared with other Layer 2 protocols or Layer 3 IP running on data centers, TRILL has thefollowing advantages:l Easy deployment: Compared with Layer 3 IP, TRILL is easier to deploy because you do

not need to configure interface IP addresses.l Loop prevention: The hop field in the TRILL header can minimize the impact of temporary

loops.l High-speed convergence: TRILL detects the network in real time, and routes can be

converged within sub-seconds.l Highly-efficient forwarding: Devices on a TRILL network use the Shortest Path First (SPF)

algorithm to generate the unicast and multicast forwarding tables and transmit traffic basedon the forwarding tables.

Basic ConceptsTable 1-1 lists the basic concepts related to a TRILL network.

Table 1-1 Basic concepts about TRILLConcept DescriptionRouting bridge (RB) Switch that runs TRILL.

Concept DescriptionDesignated routing bridge (DRB) RB that communicates with each device on

broadcast networks and sends completesequence number protocol data units(CSNPs) to synchronize all the link statedatabases (LSDBs). DRB is only exist inbroadcast network.

Appointed forwarder (AF) RB that is selected by a DRB to transmit userpackets.

Carrier VLAN VLAN that transmits TRILL data andprotocol packets.

Custom edge VLAN (CE VLAN) VLAN that is used for CE users to accessTRILL networks and that transmits Ethernetdata packets only.

1.2 TRILL Features Supported by the DeviceTRILL enables user information to be efficiently and quickly transmitted between routingbridges (RBs) and between an RB and a server.

NOTE

The CE series switches cannot terminate TRILL packets at Layer 2 and then forward them at Layer 3.

TRILL Route Selection RulesOn a TRILL network, routes are selected based on the following rules:l The Shortest Path First (SPF) algorithm is used, and the route with the smallest link cost

is selected.l Equal-cost routes (if there are) load-balance traffic. Load balancing is enabled on TRILL

networks by default.

Factors Determining the TRILL Network Convergence SpeedThe network convergence speed is critical to network performance. The factors that determinethe TRILL network convergence speed are described as follows:



4

l Interval at which neighbor status is detectedRBs periodically exchange Hello packets to maintain the neighbor relationship betweenthem. By default, if one RB does not receive any response from the other after sendingthree consecutive Hello packets, this RB considers the neighbor Down. Therefore, theinterval at which Hello packets are sent and the number of consecutive Hello packets thatare sent before an RB considers the neighbor Down determine the TRILL networkconvergence speed.

l Flooding parameters of sequence number PDUs (SNPs) and link state protocol data units(LSPs)LSPs carry status changes on networks, and SNPs carry complete or partial LSPinformation. LSPs and SNPs are periodically updated to synchronize link state databases(LSDBs) so that nickname forwarding tables can keep pace with network changes.The LSP refresh interval, sending interval, maximum lifetime, and SNP sending intervaldetermine the broadcast network convergence speed. The LSP retransmission intervaldetermines the P2P network convergence speed.

l SPF calculation intervalAfter LSDBs are synchronized, RBs perform the SPF algorithm to calculate routes.Therefore, SPF calculation interval determines the network convergence speed.

TRILL NSRNSR ensures uninterrupted traffic transmission if a fault occurs on the control plane and a backupcontrol plane is available to take over the traffic. During the switchover, the fault is transparentto the control plane of a neighbor.

TRILL Authentication ModesTRILL authentication improves network security.TRILL supports simple, MD5, hmac-sha256 and keychain authentications. Hello packets, LSPs,and SNPs carry authentication information, and packets that fail the authentication are discarded.TRILL authentication prevents unauthorized users from tampering with packets and improvesnetwork security.

1.3 Configuring Basic TRILL FunctionsBasic TRILL functions allow all devices to communicate with each other on TRILL networks.

Applicable EnvironmentThis section describes how to configure basic TRILL functions to allow switches tocommunicate with each other on Layer 2 networks.The configurations of basic TRILL functions involve enabling TRILL globally and then on eachinterface.

1.3.1 Enabling TRILL GloballyContext

Before configuring other TRILL features, enable TRILL globally. Configure the followingadditional functions to facilitate future management and maintenance:l Configure the administrative VLAN to allow administrators to maintain and manage

routing bridges (RBs) using remote login.l Configure a network entity title (NET) or dynamic hostname because TRILL uses the MAC

address of each RB as its system ID by default, and the MAC address is difficult tomemorize.

l Configure a nickname for each RB to avoid nickname conflicts and facilitate management.The nickname of each RB must be unique on TRILL networks. However, a nickname isgenerated automatically by default, which may result in nickname conflicts.

l Configure RB interface modes based on their roles on TRILL networks.

ProcedureStep 1 Run:

system-view

The system view is displayed.Step 2 Run:

trill

TRILL is enabled globally, and the TRILL view is displayed.



6

Step 3 Run:carrier-vlan carrier-vlanid

A Carrier VLAN ID is specified.Step 4 (Optional) Run:

network-entity net

The NET is configured.NOTE

The NET must be unique on TRILL networks. Otherwise, route flapping may occur.

Step 5 (Optional) Run:nickname nicknamevalue [ priority priorityvalue ] [ root-priority rootpriorityvalue ]

A nickname is configured.NOTE

The nickname must be unique on a network. If a nickname conflict occurs, TRILL performs either of thefollowing operations:l If the nickname conflicts with an automatically generated nickname, the RB with the lowest priority

generates a new nickname.l If the nickname conflicts with a configured nickname, the nickname of the RB with the lowest priority

is suppressed and is not advertised to other RBs.

Step 6 (Optional) Run:port-mode { access | hybrid | p2p | trunk }

An interface mode is configured.NOTE

By default, the interface mode is trunk. Configure an interface mode based on the following rules:l Configure the interface mode as access if the interface is located at the edge of a TRILL network to

connect to users.l Configure the interface mode as trunk if the interface is located within a TRILL network and you want

the interface to transmit TRILL packets.l Configure the interface mode as p2p if the interface connects RBs on a P2P network.l Configure the interface mode as hybrid if you want the interface to connect to users and transmit

TRILL packets.In a stack scenario, if the interface mode is hybrid, the interface may not forward packets. Therefore, thehybrid mode is not recommended.

Step 7 (Optional) Perform the following steps to configure a CE VLAN if an RB is located at the edgeof a TRILL network and connects to a server.1. Run:

quitExit from the TRILL view.

2. Run:vlan vlan-idA VLAN is created, and the VLAN view is displayed.

3. Run:quit

Exit from the VLAN view.4. Run:

trillThe TRILL view is displayed.

5. Run:ce-vlan { vlan-id1 [ to vlan-id2 ] } & The CE VLAN ID is specified.

NOTE

A CE VLAN must be a VLAN created using the vlan command. A VLAN cannot function as botha CE VLAN and a Carrier VLAN.

Step 8 (Optional) Run:trill-name symbolic-name

A dynamic hostname is configured.After you run this command, the configured symbolic-name is carried in LSPs and advertisedto other devices in the same domain. When you use display commands to check TRILLinformation on these devices configured with dynamic hostname mapping, the system ID isreplaced with symbolic-name.

Step 9 (Optional) Perform the following steps to configure a admin VLAN to allow administrators tomaintain and manage RBs through remote.1. Run:

quitExit from the TRILL view.

2. Run:vlan vlan-idA VLAN is created, and the VLAN view is displayed.

3. Run:quitExit from the VLAN view.

4. Run:trillThe TRILL view is displayed.

5. Run:admin-vlan vlan-idThe administrative VLAN ID is specified.

NOTE

A admin VLAN must be a VLAN created using the vlan command. A VLAN cannot function asboth a admin VLAN and a Carrier VLAN.

6. Run:quitExit from the TRILL view.

7. Run:interface vlanif vlan-idA VLANIF interface is created and the VLANIF interface view is displayed.



8

8. Run:ip address ip-address { mask | mask-length } [ sub ]

An IP address is assigned to the VLANIF interface.NOTE

The IP addresses must be in the same network segment with the edge device interfaces that directlyconnect the RB interfaces, to provide reachable nickname.

NOTE

After the administrative VLAN ID is specified, configure IP addresses for RB interfaces in theadministrative VLAN.

Step 10 Run:commit

The configuration is committed.----End

1.3.2 Enabling TRILL on an InterfaceContext

After enabling TRILL globally, enable TRILL on each interface so that RBs can establish TRILLneighbor relationships.TRILL can be enabled only on trunk or hybrid interfaces. Access interfaces can only be usedfor user access and cannot have TRILL enabled.TRILL interfaces are classified into four modes, the default of which is trunk. You can configureinterface modes for RBs based on their roles on TRILL networks to reduce the number of packetsto be processed and to use bandwidth and system resources more efficiently.In addition, DRBs on broadcast networks must have relatively high levels of performancebecause they need to communicate with each RB. Therefore, configure a DRB priority for eachinterface so that RBs with higher DRB priorities can be elected as DRBs.


system-view

The system view is displayed.NOTE

Perform either of the following operations to enable TRILL on interfaces:l Perform Step 2 if you want to enable TRILL on a small number of interfaces or on interfaces with

nonconsecutive sequence numbers.l Perform Step 3 if you want to enable TRILL on a large number of interfaces or on interfaces with

consecutive sequence numbers.

Step 2 Run:interface interface-type interface-number

The interface view is displayed.



9

Step 3 Perform the following steps:1. Run:

port-group port-group-nameAn interface group is created.

2. Run:group-member { interface-type interface-number1 [ to interface-type interface-number2 ] } & An interface number range is specified for the interface group.

Step 4 Run:trill enable [ port-mode { access | hybrid | p2p | trunk } ]

TRILL is enabled on the interface or interface group and the interface mode is configured..NOTE

l If the interface is Down, enable the TRILL process in the interface view and run the undo shutdowncommand to restart the interface.

l By default, the interface mode is trunk. Configure an interface mode based on the following rules:l Configure the interface mode as access if the interface is located at the edge of a TRILL network

to connect to users.l Configure the interface mode as trunk if the interface is located within a TRILL network and you

want the interface to transmit TRILL packets.l Configure the interface mode as p2p if the interface connects RBs on a P2P network.l Configure the interface mode as hybrid if you want the interface to connect to users and transmit

TRILL packets.l In a stack scenario, if the interface mode is hybrid, the interface may not forward packets. Therefore,

the hybrid mode is not recommended.l When both the stacking and TRILL functions are enabled on a device, you can only configure load

balancing based on the MAC addresses of user packets in the LAG load balancing profile, if LAG isconfigured on an access-side interface of the TRILL network.

Step 5 (Optional) Run:trill drb-priority priority

A DRB priority is configured on the interface.By default, the DRB priority of an interface is 64. If you want the RB to be elected as a DRB,configure a relatively high DRB priority.

Step 6 Run:commit


1.3.3 (Optional) Configuring a Link Cost for a TRILL InterfaceContext

Because TRILL uses the Shortest Path First (SPF) algorithm to generate unicast and multicastforwarding tables, the link cost is crucial to route selection. If you adjust the link costs of TRILLinterfaces, routes are reselected. The following link costs take effect on a TRILL interface inascending order of priority:



10

l Automatically calculated link cost: By default, the calculation formula is as follows: Linkcost of the interface = Bandwidth reference value/Interface bandwidth. You can change thebandwidth reference value to adjust the link cost of an interface.

l Global link cost: the link cost shared by all TRILL interfaces on an RBl Interface link cost: the link cost configured for a specified TRILL interface

Procedurel Adjust the automatically calculated link cost.

1.4 Implementing Refined Control over TRILL RouteSelection

To better control route selection and use network resources more efficiently, you can implementrefined control over Transparent Interconnection of Lots of Links (TRILL) route selection.

Applicable EnvironmentAfter you configure basic TRILL functions, devices on the network use TRILL to communicatewith each other. TRILL uses the Shortest Path First (SPF) algorithm to generate unicast andmulticast forwarding tables based on link state databases (LSDBs) and transmits traffic basedon these forwarding tables. The TRILL mechanisms alone, however, cannot meet therequirements for network planning and traffic management on large-scale networks. BecauseTRILL uses SPF to generate unicast and multicast forwarding tables, some links with higherlink costs may be idle, while those with lower link costs may be overloaded. This load imbalancewastes a great number of network resources and affects the transmission quality. To better controlroute selection and use network resources more efficiently, you can implement refined controlover TRILL route selection.To implement refined control over TRILL route selection, perform the following operations:l 1.3.3 (Optional) Configuring a Link Cost for a TRILL Interface



12

NOTE

Adjust the link costs of TRILL interfaces when you configure basic TRILL functions becauseadjusting link costs while TRILL services are running on large-scale networks causes routerecalculation and convergence.

l 1.4.1 Selecting the DVLANl 1.4.2 Configuring TRILL Load Balancing

Pre-configuration TaskBefore implementing refined control over TRILL route selection, complete the following task:l 1.3 Configuring Basic TRILL Functions

Configuration ProceduresSelect one or more configurations tasks.

1.4.1 Selecting the DVLANContext

In network planning, an operator may deploy multiple Carrier VLANs on the TRILL network.However, only one of them can function as the DVLAN. In most cases, the designated routingbridge (DRB) selects one Carrier VLAN as the DVLAN, but the DVLAN selected in this waymay not conform to the network planning. In this situation, select a DVLAN based on the networkplanning. After a DVLAN is selected, only the DVLAN can transmit TRILL data packets.

The interface view is displayed.Step 3 Run:

trill designated-vlan vlan-id

The DVLAN is specified.NOTE

The DVLAN must be a Carrier VLAN.

Step 4 Run:commit




13

1.4.2 Configuring TRILL Load BalancingContext

On large-scale TRILL networks, multiple equal-cost routes to the same destination may beavailable. Without load balancing, traffic is transmitted randomly, which results in poor trafficmanagement. If these equal-cost routes load-balance traffic, network resource usage increasesand network congestion along overloaded routes is prevented.


system-view


trill

The TRILL view is displayed.Step 3 Run:

maximum load-balance number

The maximum number of equal-cost routes for load-balancing is configured.NOTE

By default, the maximum number of equal-cost routes for load balancing is 16.If equal-cost routes outnumber the configured value on a TRILL network, the TRILL network selects theequal-cost routes in the following sequence:l Route with the smaller outbound interface indexl Route whose next hop RB has the smaller system ID

Step 4 Run:commit



l Run the display trill interface [ verbose ] command to check TRILL interface information.l Run the display trill route [ nickname ] command to check information about TRILL

unicast routes.----End

1.5 Adjusting the TRILL Network Convergence SpeedShortest Path First (SPF) parameters and link state protocol data unit (LSP) fast flooding controlthe Transparent Interconnection of Lots of Links (TRILL) network convergence speed.



14

Applicable EnvironmentThe network convergence speed is critical to network performance. TRILL boasts high-speedconvergence, but when TRILL is deployed on large-scale data center networks, networkcomplexity slows down the convergence. In this situation, use the following approaches listedin Table 1-3 to adjust the network convergence speed.

Table 1-3 Approaches to adjust the TRILL network convergence speedTRILL Running Phase Approaches to Adjust the TRILL

Network Convergence SpeedNeighbor relationship establishment Adjust the interval at which neighbor status

is detected by changing the interval at whichHello packets are sent and the hold time ofneighbors.

Link state database (LSDB) synchronization Adjust flooding parameters of sequencenumber PDUs (SNPs) and LSPs.

SPF algorithm Adjust the SPF calculation interval.

Pre-configuration TaskBefore adjusting the TRILL network convergence speed, complete the following task:l 1.3 Configuring Basic TRILL Functions


1.5.1 Adjusting the Interval at Which Neighbor Status Is DetectedContext

Routing bridges (RBs) exchange Hello packets to establish neighbor relationships on TRILLnetworks. After establishing neighbor relationships, RBs send Hello packets at intervals tomaintain the neighbor relationships and detect neighbor status. If a local RB does not receiveany Hello packets from a neighboring device within a specified period (hold time), the local RBconsiders the neighboring device Down and refreshes the local routing table. As a result, routesare re-converged on the TRILL network. Perform the following operations to adjust the intervalat which neighbor status is detected:l Adjust the interval at which Hello packets are sent.l Configure the holding multiplier for neighboring devices.

Procedurel Adjust the interval at which Hello packets are sent.

1. Run:system-view

commit

The configuration is committed.l Configure the holding multiplier for neighboring devices.

1. Run:system-view




trill timer holding-multiplier number

The holding multiplier is configured. The formula to calculate the hold time is asfollows: Hold time = Holding multiplier x Interval at which Hello packets are sent.

4. Run:commit


1.5.2 Adjusting Flooding Parameters of SNPs and LSPsContext

When the network status changes, routing bridges (RBs) send LSPs to advertise these changeson TRILL networks. SNPs carry complete or partial LSP information and are used to synchronizeLSDBs. SNPs are classified into complete SNPs (CSNPs) and partial SNPs (PSNPs). CSNPscarry summaries of all LSPs in LSDBs, while PSNPs list only the sequence numbers of recentlyreceived LSPs.The LSDB synchronization process varies with the network type. The LSDB synchronizationprocesses on broadcast and P2P networks are described as follows:l On broadcast networks, if a designated routing bridge (DRB) receives an LSP that is

unavailable in its LSDB, the DRB adds this LSP to its LSDB and sends CSNPs at intervalsto broadcast the updated LSDB. After receiving the CSNP, each RB checks whether itsLSDB is synchronous with the CSNP. If they are asynchronous, the RB sends a PSNP torequest the LSPs that are unavailable in its LSDB.

l On P2P networks, CSPNs are sent only when two ends are establishing an adjacency forthe first time. The local RB sends a CSNP, and the remote RB replies with a PSNP. If the



16

CSNP and the LSDB of the remote RB are asynchronous, the remote RB sends a PSNP torequest the LSPs that are unavailable in its LSDB. After receiving the PSNP, the local RBreplies with the required LSPs and starts the LSP timer at the same time. If the local RBdoes not receive any PSNP as a response from the remote RB before the LSP timer expires,the local RB re-sends the LSP.

To speed up LSDB synchronization, adjust the following parameters of SNPs and LSPs:l Set the interval at which CSNPs are sentl onfigure the intelligent timer to control LSP generationl Set the refresh interval for LSPsl Set the maximum lifetime for LSPsl Set the minimum interval at which LSPs are sentl Set the interval at which LSPs are retransmitted over a P2P link

Procedurel Set the interval at which CSNPs are sent.

1. Run:system-view

The configuration is committed.l Configure the intelligent timer to control LSP generation.

1. Run:system-view


trill


timer lsp-generation max-interval [ init-interval [ incr-interval ] ]

The intelligent timer is configured to control LSP generation.The parameters are described as follows: If you specify max-interval only, the intelligent timer functions as an ordinary one-

time triggering timer, and LSPs are generated at the interval specified by max-interval.

If you specify both max-interval and init-interval, init-interval determines thedelay in generating an LSP for the first time, and from the second time on, max-interval determines the delay in generating an LSP. After the delay remains at thevalue specified by max-interval for three times or the TRILL process is restarted,the delay decreases to the value specified by init-interval.

If you specify max-interval, init-interval, and incr-interval, init-intervaldetermines the delay in generating an LSP for the first time, and incr-intervaldetermines the delay in generating the same LSP for the second time. From thethird time on, the delay in generating an LSP doubles each time until the delayreaches the value specified by max-interval. After the delay remains at the valuespecified by max-interval for three times or the TRILL process is restarted, thedelay decreases to the value specified by init-interval.

1.5.3 Adjusting the SPF Calculation IntervalContext

When the network status changes, TRILL performs the SPF algorithm to refresh routeinformation. If the network is unstable, TRILL performs frequent route calculation, whichconsumes a large number of CPU resources and affects the running of services.



19

To solve this problem, configure an intelligent timer to control the SPF calculation interval.Specifically, set the SPF calculation interval to a small value to speed up TRILL routeconvergence, and set the interval to a large value after the TRILL network becomes stable.

timer spf max-interval [ init-interval [ incr-interval ] ]

The SPF intelligent timer is configured.Specify the parameters based on the following rules:l If you specify max-interval only, the intelligent timer functions as an ordinary one-time

triggering timer, and TRILL performs the SPF algorithm after routes are converged and max-interval expires.

l If you specify both max-interval and init-interval, init-interval determines the delay in SPFcalculation for the first time, and from the second time on, max-interval determines the delayin SPF calculation. After the delay remains at the value specified by max-interval for threetimes or the TRILL process is restarted, the delay decreases to the value specified by init-interval.

l If you specify max-interval, init-interval, and incr-interval, init-interval determines the delayin SPF calculation for the first time, and incr-interval determines the delay in SPF calculationfor the second time.

1.6 Improving TRILL Network SecurityTransparent Interconnection of Lots of Links (TRILL) authentication can improve TRILLnetwork security.

Applicable EnvironmentAs the Internet develops, there has been considerable growth in all types of data, voice, andvideo information exchanged on networks, requiring higher information security than before.Therefore, operators must protect data packets from being intercepted or modified by attackersand prohibit unauthorized users from accessing network resources.A TRILL authentication-enabled device adds an authentication field to encapsulate a packetbefore sending it to ensure network security. After receiving a TRILL packet from a remoterouting bridge (RB), the local RB discards the packet if the authentication password in the packetis different than the local one. This authentication mechanism protects the local RB againstpackets sent from unauthorized users. TRILL supports packet authentication and interfaceauthentication.

Pre-configuration TaskBefore configuring TRILL authentication, complete the following task:l 1.3 Configuring Basic TRILL Functions


1.6.1 Configuring TRILL Packet AuthenticationContext

In most cases, routing bridges (RBs) do not encapsulate authentication information into TRILLpackets before sending them or authenticate received TRILL packets. Therefore, networks areopen to attacks. To improve network security, configure TRILL authentication.In TRILL packet authentication, link state protocol data units (LSPs) and sequence numberPDUs (SNPs) carry authentication information. After receiving the packets, the remote RBauthenticate them and discard those that fail the authentication.RBs in the same area must share the same area authentication mode and password so that TRILLpackets can be properly flooded. Whether packets pass the authentication does not affect theestablishment of neighbor relationships.

Step 2 Run:trill


area-authentication-mode { {simple | md5 | hmac-sha256 key-id key-id } { [ cipher ] password-key | plain password } | keychain keychain-name } [ snp-packet { authentication-avoid | send-only } | all-send-only ]

The authentication mode is configured.Specify the parameters based on the following descriptions:l If you want RBs to encapsulate the authentication information into LSPs and SNPs before

sending them, and authenticate received LSPs and SNPs and discard packets that fail theauthentication, do not specify snp-packet or all-send-only.

l If you want RBs to encapsulate authentication information only into LSPs before sendingthem and authenticate only received LSPs, specify snp-packet authentication-avoid.

l If you want RBs to encapsulate the authentication information into LSPs and SNPs beforesending them and authenticate received LSPs only, specify snp-packet send-only.

l If you want RBs to encapsulate the authentication information into LSPs and SNPs beforesending them but not to perform authentication, specify all-send-only.

Step 4 Run:commit


1.6.2 Configuring TRILL Interface AuthenticationContext

In TRILL interface authentication, Hello packets carry authentication information configuredon the interface of the local RB. After receiving the packets, the remote RB authenticate themand discard those that fail the authentication.If TRILL interface authentication is configured on both ends, they must share the sameauthentication mode and password so that neighbor relationships can be established betweenthem.

The interface view is displayed.Step 3 Run:



22

trill authentication-mode { { simple | md5 | hmac-sha256 key-id key-id } { [ cipher ] password-key | plain password } | keychain keychain-name } [ send-only ]

The authentication mode and password are configured on the interface.Specify the parameters based on the following descriptions:l If you want a TRILL interface to encapsulate authentication information into Hello packets

before sending them but not to authenticate received Hello packets, specify send-only.l If you want a TRILL interface to encapsulate authentication information into Hello packets

before sending them and also authenticate received Hello packets, do not specify send-only. In addition, configure the same authentication information for all TRILL interfaceswithin the same VLAN to ensure proper communication.

1.8 Configuration ExamplesThis section provides several TRILL configuration examples. The configuration examplesinclude networking requirements, precautions, the configuration roadmap, and the configurationprocedure.

1.8.1 Example for Configuring Basic TRILL FunctionsNetworking Requirements

Data centers require increasingly higher transmission reliability on networks that have a largenumber of servers. TRILL, with easy deployment, highly-efficient forwarding, high-speedconvergence, and loop prevention, provides a solution to data centers. After TRILL isconfigured, users can communicate with servers through devices on Layer 2 networks.On large networks, there may be multiple valid routes to the same destination. According to theShortest Path First (SPF) algorithm, however, only the route with the smallest cost is selectedas the optimal route to transmit packets. This implementation may result in unbalanced trafficon different routes. To address this problem, configure the number of equal-cost routes toimplement load balancing.As shown in Figure 1-2, the five TRILL-capable RBs belong to the same VLAN. A TRILLnetwork is used to implement communication between servers, and between servers and theLayer 3 network. RBs on the TRILL network use the SPF algorithm to generate the unicast andmulticast forwarding tables and transmit traffic based on the forwarding tables. By default, equal-cost routes (if any) load-balance traffic.
