I'd be very interested to hear others opinions on this. You have a datacenter environment with L2 boundaries at end of row aggregators, then L3 back to the core and edge. You have 6500 service module switches hanging off the core housing ACE and FWSM modules. You want to offer firewalling and load-balancing services to servers around the datacenter.
What is the current best practice ways of resolving the L2 adjacency requirement that the firewalling and load-balancing services impose? L2TPv3? EoMPLS? Any relevant advice, deployment examples, whitepapers etc would be much appreciated!
Thanks for any replies,
