COMMAND LINE INTERFACE

to the router. When the router receives these messages, it records all the downstream routers for the default route.

•When multicast traffic with an unknown source address (i.e., not found in the route table) is received on the default upstream route interface, the router forwards this traffic out through the other interfaces (with known downstream routers). However, when multicast traffic with an unknown source address is received on another interface, the router drops it because only the default upstream interface can forward multicast traffic from an unknown source.

Example

Console(config-router)#default-gateway 10.1.0.253

Console(config-router)#

ip dvmrp
