To set an administrative RIP distance to a specified value, use the distance router configuration command.
Command Purpose
distance distance-value [prefix] [access-
list-name] Assign an administrative distance.
5.4.7 Generate a Default Route
You can force an autonomous system boundary router to generate a default route into an RIP routing domain.
Whenever you specifically configure the redistribution of routes into an RIP routing domain, the router automatically
becomes an autonomous system boundary router. However, an autonomous system boundary router does not, by
default, generate a default route into the RIP routing domain.
To force the autonomous system boundary router to generate a default route, perform the following task in router
configuration mode:
Command Purpose
default-information originate Forces the autonomous system boundary router to generate
a default route into the RIP routing domain.
5.4.8 Filtering Routing Information
The following tasks let you filter routing protocol information:
• Suppress the sending of routing updates on a particular router interface in order to prevent other systems on an
interface from dynamically learning about routes
• Suppress networks from being advertised in routing updates in order to prevent other routers from learning a
particular device’s interpretation of one or more routes
• Apply an offset to routing metrics in order to provide a local mechanism for increasing the value of routing
metrics
Suppress Routing Updates through an Interface
To prevent other routers on a local network from dynamically learning about routes, you can keep routing update
messages from being sent through a router interface. This feature applies to all IP-based routing protocols except
BGP.
Command Purpose
passive-interface interface-name Suppress the sending of routing updates through a router
interface.
Suppress the Advertising of Route Updates
In order to filter routing information, you can suppress the networks listed in updates from being advertised and
processed by a routing process. If you apply access-lists or prefix-lists to a chosen interface, the routing path in an
update is filtered on the lists.
