IGMP
IGMP relay/proxy specification and environment:
Support IGMP proxy/relay function for ADSL modem, based on the following
requirement and case:
On CO side, there must be at least one IGMP querier (router) present. IGMP
querier will send IGMP query packet. The ADSL modem is responsible to relay
these IGMP query to Ethernet.
End-user multicast application device send IGMP report while receiving IGMP
query or being activated by user, the ADSL modem should be responsible to
proxy (that is, change source IP to ADSL modem’s WAN IP) the IGMP report to
ADSL WAN side, include all PVCs. The same case is for IGMP leave packet.
Not necessary to relay multicast routing between two ADSL PVCs or two
interfaces in LAN side.
Special purpose multicast packet (such as RIP 2 packet) should run without
interference.
