VPC Not Working

[CiscoBrownBelt]

So I have configured VPC on 2 Nexus.

Here is what I get. Any ideas what may be wrong?

Since the Secondary Nexus is a failover (identical configs) I can't NO SHUT the SVIs or I get duplicate errors. Is this done once VPC is fully working:

SiteBB1_ServerAccessSw1# sh vpc br

Hi

Do a "show vpc consistency-parameters global" it will show the reason for inconsistency.

Maybe the reason is you have shutdown the svi, if so, configure the svi:s with different ip:s and use hsrp instead, then you can have the svi:s with "no shut" on both nexus.

Yes I was doing the show vpc consistency but overlooking that I had a vrf and another SVI on 1 switch but not the other. All is good now.

Maybe off the subject, but if I have just 2 Nexus in a VPC domain (meaning I want them to be redundant), I would need to configure all SVI as HSRP. This is the only way to do it other than creating routing protocols correct?

Yes, you are correct. Otherwise, if you are using port-channels and vpc to connect things, they will not work properly.
