6.1.5 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.
