RIP 119
Configuring RIP to Filter the Received Routes
Configuring RIP to Filter the Distributed Routes
By default, RIP will not filter the received and distributed routing information.
â– The filter-policy import command filters the RIP routes received from its
neighbors, and the routes that cannot pass the filter will not be added to the
routing table, and will not be advertised to the neighbors.
â– The filter-policy export command filters all the advertised routes,
including routes imported by using the
import-route command, and RIP
routes learned from the neighbors.
â– If the filter-policy export command does not specify which route is to be
filtered, then all the routes imported by the
import-route command and the
transmitted RIP routes will be filtered.
