IPv6 multicast with MLDv1 and MLDv2 in EVPN-VXLAN-centrally routed bridging overlay fabrics

You can configure multicast with Multicast Listener Discovery versions 1 (MLDv1) and 2 (MLDv2) in an Ethernet VPN?Virtual Extensible LAN (EVPN-VXLAN) centrally routed bridging (CRB) overlay fabric. With this feature, you can enable multihoming for the following IPv6 multicast traffic use cases:

• Intra-VLAN forwarding
• Inter-VLAN routing

MLD multicast works with these multicast optimizations:

• MLD snooping
• Selective multicast Ethernet tag (SMET) forwarding
• Assisted replication (AR)

These devices process:

• MLDv1 reports as any-source multicast (ASM) (*,G) reports
• MLDv2 reports in one of these modes:
• Any-source multicast (ASM) (*,G) reports by default
• Source-specific multicast (SSM) (S,G) reports (only if you explicitly configure this mode)
