We have a spine and leaf topology, where we have several VRFs. We’re currently using VRF-lite, with EBGP peerings per-VRF between spines and leaves.
We are using Multicast in all VRFs. The Rendezvous Points are Loopback addresses in the Spines, and they use anycast-rp addresses. PIM neighborhoods are being formed, everything works as expected.
Now we’ve decided to test a EVPN configuration. We’ve configured EVPN with 1 interface Vxlan per device, and 1 VNI per VRF. We don’t have stretched VLANs (so there are no VNIs for VLANs), since we just need to advertise EVPN ipv4 prefixes.
We are essentially using VxLAN + EVPN to build a L3VPN. This shows all the advertised prefixes.
All VRF routes are being propagated across all devices, and there is IP reachability between all of them, to all destinations, including the Spine Loopback IPs that will serve as RPs. However, now the PIM neighborhoods don’t come up now.
Can you tell us what needs to be done so multicast can work on the overlay VRFs?
