I have a question about exporting policies from a Multi-Site External Network in NDFC 3.2.2m. I have to rebuild the core routers because I already had VPC built when I imported them, and it won't let me add a VPC port channel if the VPC wasn't built ...

I think @balaji.bandi has a point here. What is causing NDFC to see that as an intra-fabric is is CDP/LLDP packets being passed between the two switches. You could turn off CDP/LLDP on the interfaces on one or both sides, and then that automatically ...
