 Note:
The router enabled to advertise a default route does not receive default routes from RIP
neighbors.
2.3.5 Configuring Inbound/Outbound Route Filtering
The device supports route filtering. You can filter routes by configuring the inbound and
outbound route filtering policies via referencing an ACL or IP prefix list. You can also
configure the router to receive only routes from a specified neighbor.
Follow these steps to configure route filtering:
To do… Use the command… Remarks

Enter RIP view rip [ process-id ] ––
Configure the
filtering of incoming
routes
filter-policy { acl-number | gateway
ip-prefix-name | ip-prefix ip-prefix-name
[ gateway ip-prefix-name ] } import
[ interface-type interface-number ]
Required
Not configured
by default
Configure the
filtering of outgoing
routes
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ protocol
[ process-id ] | interface-type
interface-number ]
Required
Not configured
by default
 Note:
z Using the filter-policy import command filters incoming routes. Routes not passing
the filtering will be neither installed into the routing table nor advertised to neighbors.
z Using the filter-policy export command filters outgoing routes, including routes
redistributed with the import-route command.
2.3.6 Configuring a Priority for RIP
Multiple IGP protocols may run in a router. If you want RIP routes to have a higher
priority than those learned by other routing protocols, you can assign RIP a smaller
priority value to influence optimal route selection.
Follow these steps to configure a priority for RIP:
