service-id based on the MVR from-vpls definition. Another difference between the VPLS Layer 2
flooding list and IGMP lists is that many IGMP lists may exist (each associated with a different [s,g]
record) and the lists may contain residential SAPs. The SAP chaining and replication behavior is
similar to the VPLS Layer 2 flooding list.
IP multicast packets ingressing the vpls-service-id must match either a [*,g] or [s,g] record to be
associated with the record’s egress IP multicast IGMP flooding list. A [*,g] record will match any
ingress IP multicast packet destined to the class D destination IP address represented by “g”. An [s,g]
record will match any ingress IP multicast packet with a source IP address matching “s” and a
destination IP address matching “g”. In the case that a packet could match both a [*,g] and [s,g]
record, the [s,g] record takes precedence. Each [*,g] and [s,g] record has its own IGMP flooding list.
The list will only appear on an egress forwarding plane (MDA) when a member of the list (VPLS
interface) exists on the forwarding plane.
