I am not sure what you exactly are looking for, but I recommend you to read the following articles:

We have servers connected to nexus7K through enhanceVPC. Now there is need to extend L2 to another data-center where we don't have nexus7K - so we need to uses NSX to do that. For that we need to run routing protocol (dynamic or static) between NSX router and Nexus7Ks. We are using F3 linecards and running SW version 7.2.2.

Are using VMware NSX? if yes, both  NSX and the 7k support routing protocols as well as static routes.

So, that should not be an issue.

Yes NSX virtual router  and N7K support routing but the question is whether routing supported over vpc. If the connections are through over non-vpc then there is no problem.

I am attaching Cisco's recommendation.

That’s one thing about the Cisco forums that irritates me. No one ever wants to proved a real cutdown educated answer. They just refer documents. It’s easy to throw whitepapers I guess than rather EXPLAIN in your own words. It shows a real lack of technical understanding of one cannot convey and break down a concept.

 

It’s a simple question. If the core be it a Nexus 7k pair running 7.2 to a end-host, can an NSX edge router dynamically route to the SVI over VPC. Historically it’s been unsupported and VMWare/Cisco documents mention Cisco not supporting dynamic routing over VPC yet Cisco in other docs states with XYZ version it is.
