External multicast router for EVPN with IGMP snooping

You can configure a provider edge (PE) switch running Ethernet VPN (EVPN) to send and receive multicast traffic to an external multicast router. This implementation supports the forwarding of inter-VLAN multicast traffic without having to configure IRB interfaces. Traffic is forwarded through a Layer 3 multicast protocol such as Protocol Independent Multicast (PIM). To enable the PE switch to receive multicast traffic from the multicast router, include the multicast-router-interface statement at the [edit protocols igmp-snooping vlan vlan-name interface interface-name] hierarchy level.
