Configuring Inbound/Outbound Route Filtering; Configuring A Priority For Rip - 3Com 4510G Configuration Manual

To do...
Configure the RIP interface
to advertise a default route
The router enabled to advertise a default route does not receive default routes from RIP neighbors.

Configuring Inbound/Outbound Route Filtering

The device 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 only
routes from a specified neighbor.
Follow these steps to configure route filtering:
To do...
Enter system view
Enter RIP view
Configure the filtering
of incoming routes
Configure the filtering
of outgoing routes
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.
Using the filter-policy export command filters outgoing routes, including routes redistributed with
the import-route command.

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:
Use the command...
rip default-route { { only |
originate } [ cost cost ] |
no-originate }
Use the command...
system-view
rip [ process-id ]
filter-policy { acl-number | gateway
ip-prefix-name | ip-prefix ip-prefix-name
[ gateway ip-prefix-name ] } import
[ interface-type interface-number ]
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ protocol
[ process-id ] | interface-type
interface-number ]
