Multicast with IGMPv3 in EVPN-VXLAN centrally-routed bridging overlay fabrics

You can configure IGMPv3 multicast in an EVPN-VXLAN centrally-routed bridging overlay fabric with multihoming for the following IPv4 multicast traffic use cases:

• Intra-VLAN forwarding
• Inter-VLAN routing using:
• IRB interfaces configured with PIM
• A PIM gateway router (for Layer 2 or Layer 3 connectivity)
• An external multicast router

IGMPv3 multicast works with these multicast optimizations:

• IGMP snooping
• Selective multicast (SMET) forwarding
• Assisted replication (AR)

These devices process IGMPv3 reports in one of two modes:

• As any-source multicast (ASM) (*,G) reports by default
• As source-specific multicast (SSM) (S,G) reports only (if you explicitly configure this mode)
