COMMAND USAGE
◆ This command is used to advertise the local router’s default route
(0.0.0.0) to a neighbor. This route can be used by the neighbor to reach
the local router if no other routes are available.
◆ If several neighbors supply a default route to the same partner, the
best one will be elected according to the standard path selection
process.
◆ If a route map is specified, the default route 0.0.0.0 is advertised if the
route map contains a match ip address clause and there is a route that
matches an entry in the ip prefix-list.
