On CO side, there must be at least one IGMP querier (router) present. IGMP querier will
send IGMP query packet. The Router is responsible to relay these IGMP queries to
Ethernet.
Ethernet.
End-user multicast application device sends IGMP report while receiving IGMP query or
being activated by the user. The Router should be responsible to proxy (that is, change
source IP to Router’s WAN IP) the IGMP report to ADSL WAN side, including all PVCs.
The same case is for IGMP leave packet.

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.

field in the ATM cell header. The VPI field specifies this eight bit identifier for routing.
Range: 0-255
Default: 0
VCI: A Virtual Channel Identifier is a virtual channel that is identified by a unique numerical tag
that is defined by a 16-bit field in the ATM cell header. The purpose of the virtual channel is to
identify where the cell should travel. The VCI field specifies this 16 bit numerical tag that
determines the destination.
Range: 0-65535
Default: 35
