Hi,

Make sure you run one of the supported typologies for routing over vPC

https://www.cisco.com/c/en/us/support/docs/ip/ip-routing/118997-technote-nexus-00.html 

Also, you will need "peer-gateway" and "layer3 peer-router" configured.

Stay safe,

Sergiu

Thank you ! But just one NEXUS3548,no vpc runs .

Default bgp interface, then reconfiguration that bgp is ok, don't know why?
