RIP Route Control 295
Configuring RIP to filter or advertise the received routes
The route filtering function provided by a router enables you to configure
inbound/outbound filter policy by specifying an ACL or address prefix list to make
RIP filter incoming/outgoing routes. Besides, you can configure RIP to receive only
the RIP packets from a specific neighbor.

■ The filter-policy import command filters the RIP routes received from
neighbors, and the routes being filtered out will neither be added to the
routing table nor be advertised to any neighbors.
■ The filter-policy export command filters all the routes to be advertised,
including the routes imported by using the import-route command as well as
RIP routes learned from neighbors.
■ The filter-policy export command without the routing-protocol argument
filters all the routes to be advertised, including the routes imported by the
import-route command.
