BGP EVPN VXLAN interoperability and sticky MAC community

[DaniilK]

Hello All

We have a  VDX6740 switches. There is a BGP EVPN session with third-party switches. Everything works fine, but there is a problem with some routes.
Why are routes with a sticky MAC not installed in FIB?


This route is installed in FIB:

Hello, thank you for providing those details. I ran this past some of our engineers and they requested that you open a support case for this question so we can dig in to this a little further with you. If you can go to the Portal and open a case, they can take it from there.
