I would like to check on the possible design setup for dynamic routing via ospf for the nexus switch. My setup is as below:
N7K -----------vpc --------- N7K
|(L3 ospf) | (L3 ospf)
Besides having dedicated layer 3 interface/link aggregated (parallel routed ports) ospf between each nexus switch and each 6500 switch; I would like to check if it may be possible to create/have ospf between the N7K via the vpc/virtual peer link(without dedicated link between the N7K)? This is for redundancy in case one of the N7K uplink to the 6500 disconnects/removed such that the other nexus switch may route traffic successfully.
Any suggesstion is appreciated.
A separate link is preffered, but you don't have to have a separate link for the layer-3 connection between the 7ks. You can use an SVI and use the existing peer link to route between them using OSPF.
