Hej
I am trying to configure a EVPN E-LAN solution with A/A setup. I followed the xrdocs.io
NCS540s in the diagram have EVPN E-LAN with each other. Port towards Host-1, LinkA/B are in the same EVPN instance
Host-1 can not ping Host-2 while Link B is up.
If I take down Link B, then the ping works.
If I take down Link A, and leave Link B up, ping doesn't work again.
I am not sure what I am missing exactly, help appreciated
