how is your network connected, how is your routing taking place ?

check some guide lines : join 2 vPC domain :

It would be useful to make a drawing with the current topology you have and what you plan to make, because is not clear what you mean by "VPC 1" and "VCP 2", and how Nexus1 and Nexus2 are configured in respective to a VPC domain.

Also, here are a couple of questions which could help us in understanding your setup and desired config change:

1. What are your vpc domains and vpc peers from the domains?

2. What is your vpc peer link (peer links if there are two vpc domains)?

3. What is the vpc portchannel between the vpc domains (if you have two vpc domains)?

Take care,
