Configuring the Access Side

You can configure IGMP snooping over EVPN MPLS on the access side of an EVPN that carries multicast services for various scenarios.

Context

The configurations required for various scenarios are as follows:

A CE is single-homed to a source PE or dual-homed to source PEs on the multicast source side. In this scenario, no additional configuration is required on the access side. You must configure IGMP signaling synchronization based on BGP EVPN IGMP Join Synch routes in a BD.
A CE is single-homed to a receiver PE on the access side. In this scenario, no additional configuration is required on the access side. You must configure IGMP signaling synchronization based on BGP EVPN IGMP Join Synch routes in a BD.
A CE is dual-homed to receiver PEs on the access side. In this scenario, you must configure IGMP signaling synchronization based on BGP EVPN IGMP Join Synch routes in a BD, associate the EVI-RT extended community attributes of IGMP Join Synch routes with the BD, and enable the DF status ignoring function on non-DF nodes.
A CE is dual-homed to receiver PEs on the access side, and Layer 2 multicast services on the access side access Layer 3 multicast services. In this scenario, you must enable IGMP and PIM-SM on a VBDIF interface, configure IGMP signaling synchronization based on BGP EVPN IGMP Join Synch routes in a BD, associate the EVI-RT extended community attributes of IGMP Join Synch routes with the BD, and enable the DF status ignoring function on non-DF nodes.
