Advantages of Interim Setup

Disadvantages of the Architecture:Complex L2 Network– Multiple switch form a virtual switch across the world– Several entities managing small parts of the network– No clear demarcation points
MANLAN single point of failure for connectivity between EU and USNot Scalable High risk of broadcast stormHigh risk of asymmetric traffic
Disadvantages of Interim Setup
![Page 22: Connect communicate collaborate LHCONE in Europe DANTE, DFN, GARR, RENATER, RedIRIS LHCONE Meeting Amsterdam 26 th – 27 th Sept 11.](https://reader036.fdocuments.in/reader036/viewer/2022062504/5a4d1b607f8b9ab0599acfb2/html5/thumbnails/22.jpg)

Disadvantages for End-Sites and NRENs:Configure multiple VLANsEstablish peering with 4 routes servers operated by multiple organizations Complicated end-site requirement e.g. prefer a VLAN or configure ECMP, etcNeed to understand the LHCONE Architecture to decide if end-site wants to prefer a VLAN or use ECMP, etc.Complicated procedures/processes required to bring up new end-site connections
Disadvantages of Interim Setup
![Page 23: Connect communicate collaborate LHCONE in Europe DANTE, DFN, GARR, RENATER, RedIRIS LHCONE Meeting Amsterdam 26 th – 27 th Sept 11.](https://reader036.fdocuments.in/reader036/viewer/2022062504/5a4d1b607f8b9ab0599acfb2/html5/thumbnails/23.jpg)

Disadvantages for LHCONE Operators:Can not use another Trans-Atlantic links e.g. Frankfurt – DC linkComplicated procedure for brining up new connectionNo control over path selection for traffic from A to BDifficult for NOC engineers to troubleshoot issues in this complicated L2 topology
Disadvantages of Interim Setup

As discussed and agreed in Washington meeting L3 is the solution
Advantages of a move to a L3 implementationOperational teams familiar with L3 domain and also multi-domain managementResilience and load sharing are well knownMore control over path selection/Traffic engineeringRobust architecture demonstrated on the InternetWell established demarcation points
Move to a Scalable network

Advantages of L3 Topology
Advantages for LHCONE Operators:Less complicated procedure/process for brining up new connectionMore control over path selection/traffic engineeringMake use of additional TA capacity without introducing
Another VLAN andTwo more route servers
Advantages for LHCONE end-sites:Single interface/VLAN to LHCONESingle BGP peeringSingle Point of contact for all connectivity/peering issues

Interim solution provides TA connectivity, butIs not scalable and Not manageable
Washington Meeting agreed on L3 ImplementationT2 in Europe are ready to go the L3 way
Study group needs to agree on L3 topology and migration plan
