Step Command Remarks
3. Enable RIP to advertise a
default route. default-route { only | originate } [ cost
cost ] Optional.
Not enabled by default.
4. Return to system view. quit N/A
5. Enter interface view.
interface interface-type
interface-number
N/A
6. Configure the RIP interface
to advertise a default
route.
rip default-route { { only | originate }
[ cost cost ] | no-originate }
Optional.
By default, a RIP interface can
advertise a default route if the RIP
process is configured with default
route advertisement.
NOTE:
The router enabled to advertise a default route does not receive default routes from RIP neighbors.
Configuring inbound/outbound route filtering
The switch supports route filtering. You can filter routes by configuring the inbound and outbound route
filtering policies by referencing an ACL or IP prefix list. You can also configure the router to receive routes
only from a specified neighbor.
To configure route filtering:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. 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 ]
By default, no route filtering
policy is configured.
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.
4. Configure the filtering of
outgoing routes.
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ protocol
[ process-id ] | interface-type
interface-number ]
By default, no route filtering
policy is configured.
The filter-policy export
command filters outgoing routes,
including routes redistributed
with the import-route command.
Configuring a priority for RIP
Multiple IGP protocols can run in a router. If you want RIP routes to have a higher priority than those
learned by other routing protocols, assign RIP a smaller priority value to influence optimal route selection.
