QFABRIC-G VS QFABRIC-M
Same software release for both platforms
Same feature set
Same capabilities across nodes with the following specifics
FC interfaces only on QFX3500 Node (local Gateway)
40 G access interfaces only on QFX 3600 Node (used for 10G today with break out
cable as of today)
Can be mixed together as NNG nodes
Cannot be mixed inside RSNG
As a consequence, the following content is relevant to both Qfabric-G/M and

QFABRIC NODES
12 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
NODE GROUPS
Node groups are a new software abstraction that allow you to designate
the role of each Node device:
Server Node group (SNG)
Redundant server Node group (RSNG)
Network Node group (NNG)
Assigning a role to a node dictates it capabilities / behavior
SNG/RSNG construct allow to scale the # of states
All Node devices initially belong to individual server Node groups, can be
changed through explicit configuration
13 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
SERVER NODE GROUP
Server Node groups:
Consist of a single Node device
Run only host-facing protocols such as LACP,
LLDP, ARP, and DCBX
Typically connect to servers and storage devices
not requiring cross-Node resiliency
Node device performs RE and PFE functions LAGs
SERVER NODE GROUP
RE PFE
Default group assignment for
all Node devices
14 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
REDUNDANT SERVER NODE GROUP
Redundant server Node groups:
Consist of two Node devices
Run only host-facing protocols such as LACP,
LLDP, ARP, and DCBX
Connects to servers, networking and storage
devices requiring cross-Node resiliency
LAGs
RE (Backup) PFE
RE (Active) PFE
Redundant Server Node Group
One Node device performs RE functions and both
Node devices perform PFE functions
Paired through explicit configuration
15 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
NETWORK NODE GROUP
The network Node group:
Consists of one or more Node devices (up to eight)
Can run host and network-facing Layer 2 and Layer
3 protocols (xSTP, OSPF, BGP)
Superset of SNG/RSNG
Typically connects to routers, switches and firewalls
but can connect to all network devices

QFABRIC - LAYER 2 ONLY
Qfabric is a large flat powerful & flexible ‘location agnostic’ L2 network which
connects/stitches services/routing devices to compute and storage
• Only traffic that needs services hits the SRX (traffic steering using default
gateways
• QFabric will be used for switching all Intra-VLAN traffic
• MX routes Inter VLAN traffic that doesn’t need SRX service
• MX routes ‘outside’ and provides advance service like MPLS and VPLS.

QFABRIC – LAYER 2/3 WITH VRF
Good Platform Adaptation & Appropriate Traffic Steering
• Only traffic that needs services hits the SRX
• QFabric – will be used for switching and routing
• QFabric routes a significantly higher volume of traffic that don’t need services,
only WAN and Inter-DC traffic go to MX
More Complex Configuration
• User has to configure corresponding VRFs on QFabric and stitch zones and
VRFs to SRX
NNG Nodes required to connect SRX/MX

KEY CHALLENGES WITH LEGACY DATACENTER
- Spanning Tree used to break loops with different flavors of it:
Standard: STP/RSTP/MSTP
Proprietary: PVST+/RPVST+
- Local routing and Services deployed on different aggregation layers (FHR ?)
- Multiple PODs routed by Core layer (where will routing be at the end of the migration?)
- VLAN space overlap ?
- Routed access ?
Need to interconnect multiple L2 domains, and avoid loops !

CORE/WAN LAYER USING EIGRP 1/2?
The following can be used with Qfabric:
Overlay Model
Configure OSPF on top of EIGRP
Both IGPs running at the same time (legacy side)
Admin preference/distances keep protocols separated

CORE/WAN LAYER USING EIGRP 2/2 ?
Redistribution Model
Little more complex
Redistribution EIGRP<-> OSPF

35 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
MIGRATION (ACCESS LAYER) – RECOMMENDATIONS
- Use LACP (protects against miswiring)
- Enable xSTP on Qfabric
Edge node will send BPDU out for loop detection
BPDU-block set on all SNG/RSNG interfaces
- Disable STP on the switch uplink
Qfabric will bring down the link if BPDU are received (default setting)
Enable err-disable auto-recovery
- Set Storm Control to protect against storm ‘behind’ the Fabric
- Enable LLDP (makes it easier to operate !)
- Same recommendation applies to Bladecenters with embedded switches!
Node-2 Node-3
RSNG
36 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
MIGRATION (SERVICES)
Services clusters can be connected to SNGs or RSNGs (if no routing within Qfabric)
Same recommendations as before applies for dual homing (LACP, xSTP etc.)
Move one member of the cluster first, check, then the other one
(Qfabric = High bandwith, Low latency => Moving devices is ‘transparent’, but check the
other side…)

AND FINALLY, L3 FHR MIGRATION TO QFABRIC
Traditional Network
VRRP is required for gateway redundancy for host device
Increase gateway availability by eliminating a single point-of-failure
QFabric
"Single device" behavior (RVI)
Every node-group is capable of doing L3
VRRP is no longer needed in QFabric deployment
2 step process: disable VRRP/HSRP on existing network, and enable the routed
interface on Qfabric
May need some cleaning of arp entries…

42 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
WHY WE NEED TO ENHANCE ETHERNET
Ethernet/IP network
Is a “lossy” network – dropped frames require upper layer protocols (e.g. TCP retransmit) for recovery
Network congestion is handled by dropping frames – uses upper layer protocols (e.g. TCP windowing and slow start) to manage
Inbuilt Layer 2 mechanisms (IEEE 802.1x PAUSE) not suitable for converged networks – all traffic on the link is stopped
Storage I/O protocols (e.g. SCSI)
Requires a “lossless” connection – normal SCSI timeout and recovery is 30 seconds or more – unacceptable for business applications
Fibre Channel specifies excellent BER and mandates buffer credit scheme to eliminate frame discards due to congestion
43 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
IEEE DCB – DATA CENTER BRIDGING
Priority Flow Control (PFC) ✔
Enable multiple traffic types to share a common Ethernet with independent flow control
Allows some traffic to be given a lossless service, while other traffic uses traditional Ethernet procedures
Enhanced Transmission Selection (ETS) ✔
Enable consistent management of QoS at the connection level
Designed to facilitate multiple services sharing a common connection
Data Center Bridging Exchange Notification (DCBX) ✔
Link level Management protocol for enhanced Ethernet capabilities
Leverages 802.1AB Link Level Discovery Protocol (LLDP)
Quantative Congestion Notification (QCN)
Designed to allow upstream signaling of network congestion for policy enforcement
