Hello @Han_Sen 

What do you try to push as configuration ? Please give a little context. Thanks.

Hi, there is a MSD include N9K as BGWs(VXLAN fabric) and an N7K as route-server(external fabric), now i'm creating the inter-fabric underlay links between them and this error appears.

OK @Han_Sen 

The error suggest that this config is not allowed... 

You're probably trying to assign or connect an interface that is already part of another Inter-fabric link, vpc peer-link or any other predefined topology construct in NDFC...
