Hello,

I'm doing a lab with n9k (n9kv) and VXLAN EVPN fabric. Attached a simple layout. I configured a test l3vni but I'm unable to ping the configured anycast gateway from the vm attached to leaf1 or leaf3 vms can ping each other without problems.

leaf1:

configure profile MyNetwork_30000
  vlan 2300
    vn-segment 30000
  interface nve1
    member vni 30000
      mcast-group 239.1.1.1
  evpn
    vni 30000 l2
      rd auto
      route-target import auto
      route-target export auto
configure terminal
configure profile MyVRF_50000

EDIT: I've problems even with l2vni. I suspect the problems are related to the fact that this is a nested lab.
