Multicast Routing
IGMP (Internet Group Management Protocol) is an IP routing protocol used by
IP hosts to manage their dynamic multicast group memberships on a given
network. This protocol allows a host to inform its local router that it wants to
receive messages addressed to a specific multicast group. The SLM-5650A
modem/router can be configured to perform IGMP multicast routing functions
when required by a given network.
If this SLM-5650A is in a network that utilizes multicast routing, click on the
IGMP submenu item that appears under Routing (except for Expansion units)
to access and configure the IGMP parameters for this unit, as shown in
figure 3-45.
