IP router configuration IP network multicasting

Routers send messages from a source to a destination along a network path. This topic discusses the most common router configurations for unicast and multicast messages.

The following lists some of the more common unicast and multicast configurations:

Internet Group Management Protocol (IGMP)
A protocol for registering individual hosts in particular multicast groups and for querying group membership on particular subnets.
Distance Vector Multicast Routing Protocol (DVMRP)
A set of routing algorithms that uses a technique called reverse-path forwarding to decide how multicast packets are to be routed in the network.
Multicast Open Shortest Path First (MOSPF)
A unicast routing protocol that attempts to find the shortest path between any two networks or subnets to provide the optimal routing of packets.
Note:Note: To properly configure your routers for multicasting, refer to the router reference and configuration documentation from the manufacturer.
