The CellPipe 7130 RG will not respond to IGMP join and leave messages on the
upstream interface. The CellPipe 7130 RG only responds to IGMP query messages
on the upstream interface. The CellPipe 7130 RG sends IGMP query messages to
the hosts that are members of the query VLAN.
The CellPipe 7130 RG only sends an IGMP leave message via the upstream
interface when the last host leaves a multicast group.
