must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to
the multicast routers group.
The TELKOM ADSL 5100 supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the TELKOM ADSL 5100 queries all directly connected networks to gather
group membership. After that, the TELKOM ADSL 5100 periodically updates this information. IP
multicasting can be enabled/disabled on the TELKOM ADSL 5100 LAN and/or WAN interfaces in
the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.
