I am trying to add 2 vrfs to Nexus asuming that there are 2 different tenants connected to my leaf in EVPN VXLAN network. The thing is even when I add the second vpn, BGP only show one l2vni and the second vpn does not forward. Here is the configuration of one of the leafs and the next one is almost the same. Now is this a problem on EVE-NG or am I missing something?
