Multicast with IGMP or MLD snooping within VLANs for EVPN-MPLS

Devices support multicast with IGMP orMulticast Listener Discovery (MLD) snooping within VLANs on provider edge (PE) devices in an EVPN-MPLS multihoming environment. You can configure IGMP or MLD snooping with IGMPv2, IGMPv3, MLDv1, or MLDv2 in multiple routing instances of type evpn. Multicast receivers must be within the EVPN instance (EVI). If you have only intra-VLAN traffic, you can have the multicast sources within the EVI. (Otherwise, inter-VLAN multicast requires sources to be in an external Layer 3 PIM domain.) With this support, PE devices:

• Process IGMPv2 and MLDv1 any-source multicast (ASM) (*,G) reports by default.
• Process IGMPv3 or MLDv2 reports in ASM mode (but only if you configure IGMPv3 or MLDv2 on all interfaces that receive multicast traffic).
• Drop IGMPv3 or MLDv2 source-specific multicast (SSM) (S,G) reports.
