IP router configuration
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: To properly configure your routers for multicasting,
refer to the router reference and configuration documentation from the manufacturer. |
