Hi,
I am working on a setup to test L2 connectivity across DC connected via L3 network. I have configured VXLAN with EVPN as control plane & using ingress replication instead of multicast for peer discovery and data connectivity. While I set this on actual hardware it is working, however same config is not working on virtual NXOS image on eve-ng. I looked at various blogs and it seems to be supported on virtual images.
BGP evpn peering are up, however not able to discover peers. Any help would be appreciated.
