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.

Note: Before the IGMP mode is enabled; please go to the Miscellaneous Configuration page to enable the
IGMP proxy. Otherwise, the IGMP selection will not be valid.
7. Bridge Mode Configuration:In a typical bridged configuration, the ADSL router is transparent to
the network. It bridges the ADSL line to the Ethernet line making both side appear as a single subnet.
In this configuration, an IP address only needs to be provided to the PC. It may still be beneficial to
provide an IP address to the ADSL router for management.
Following settings are necessary when working under this mode:
1. VPI/VCI
2. Encapsulation: 1483 Bridged IP LLC
3. Bridged: Enabled
4. NAT Configuration: Disabled
5. LAN DHCP Server: Disabled
Please see scenario 1: Bridge Mode Configuration Table in Appendix for more detail configuration.
8. Router Mode Configuration:In a typical routed configuration, the ADSL router is treated as a
separate device on the network that the PC and DSLAM send packets to. The Ethernet and ADSL
networks are configured as separate IP subnets. The PC must have the ADSL router set up as its
default gateway. Descriptions of the protocols supported in this mode of operation are discussed in the
next sections.
