we are trying to implement a new solution for a client of ours who has purchased a pair of nexus 5596UP devices.
We have this topology attached in jpeg. They want to use the pair of 5k's for local lan and WAN connectivity.
Customer wants a VPC setup between the pair of nexus 5k's beucase at some point they will want to purchase FEX modules and VPC servers directly, in which case the VPC will be required (VPC Vlans L3 will terminate on 5k's using HSRP).
1. Can I have the same vlan with SVI built on each nexus and pass the vlan across the peer link so I can build IBGP and peer EBGP as per the diagram. Will this work?
2. Is it possible to build a layer 3 link from each nexus to remote PE device and then setup another SVI on each nexus and allow that accross the peer link? Would this configuration work and would traffic pass across the peer link for IBGP connectivity?
3. Or can I have it as per question 1 above and use a seperate port-channel (non-vpc) between the Nexus 5k pair to trunk the vlan across?
What is the best design around this kind of solution?
The alternative is to have the Layer 2 switch connect to both Nexus 5k's without port-channel and let spanning tree manage the loop. In this case would I need to build another trunk between the 5k's or could I just allow the vlan across the VPC Peer link.
Thanks a lot in advance.
