The following IGMP snooping considerations apply:
Layer 2 multicast is supported in VPLS services.
IGMP snooping is not supported for VCs (either VC-Ether or VC-VLAN) with control-word enabled.
IGMP snooping fast leave processing can be enabled only on SAPs and SDPs. IGMP snooping proxy summarization is enabled by default on SAPS and SDPs and cannot be disabled. Proxy summarization and fast leave processing are supported only on SDPs whose VC are configured to use vc-type ether and do not have control-word enabled.
IGMP filtering using policies is available on SAPs and SDPs. It is supported only on SDPs whose VC are configured to use vc-type ether and do not have control-word enabled.
Dynamic learning is only supported on SDPs whose VC are configured to use vc-type ether and do not have control-word enabled.
SDPs that are configured to use VC of type vc-vlan that need to be router ports must be configured statically. Multicast group memberships for such SDPs must be configured statically. Dynamic learning is not available for these SDPs.
IGMP snooping is not supported for control word-enabled SDPs.
