Description
Accept and process only (S,G) reports for source-specific multicast (SSM) groups when:
You configure Internet Group Management Protocol (IGMP) snooping for IGMP version 3 (IGMPv3) with IPv4 multicast traffic in an EVPN network.
You configure Multicast Listener Discovery (MLD) snooping for MLD version 2 (MLDv2) with IPv6 multicast traffic in an EVPN network.
Devices use IGMP and MLD to discover and indicate interest in multicast groups. IGMP or MLD snooping restricts the forwarding of multicast traffic to only those interfaces in a bridge domain (VLAN) that have interested listeners.
By default, when IGMP snooping or MLD snooping is enabled, the device accepts and processes (*,G) (any-source multicast [ASM]) reports for:
-
IGMP version 2 (IGMPv2)
-
IGMPv3
-
MLD version 1 (MLDv1)
-
MLDv2
IGMPv3 and MLDv2 also support (S,G) source-specific multicast (SSM) reports and queries, but we don't support accepting and processing both (*,G) and (S,G) reports at the same time.
When you enable the evpn-ssm-reports-only option with
IGMP snooping or MLD snooping, the device honors only IGMPv3 or
MLDv2 (S,G) reports. The device drops any (*,G) reports for IGMPv2,
IGMPv3, MLDv1, or MLDv2.
