Advertising a Default Route 
You can configure RIP to advertise a default route with a specified metric to RIP neighbors. 
In RIP view, you can configure all the interfaces of the RIP process to advertise a default route; in 
interface view, you can configure a RIP interface of the RIP process to advertise a default route. 
The latter takes precedence over the former on the interface. 
If a RIP process is enabled to advertise a default route, to disable an interface of the RIP process 
from default route advertisement, you can use the rip default-route no-originate command on the 
interface. 
Follow these steps to configure RIP to advertise a default route:

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. 
 
 
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… 
Use the command…
