Routing Information Protocol | 881

Control RIP routing updates

By default, RIP broadcasts routing information out all enabled interfaces, but you can configure RIP to 
send or to block RIP routing information, either from a specific IP address or a specific interface. To 
control which devices or interfaces receive routing updates, you must configure a direct update to one 
router and configure interfaces to block RIP updates from other sources. 

To control the source of RIP route information, use the following commands, in the ROUTER RIP mode: 

Another method of controlling RIP (or any routing protocol) routing information is to filter the information 
through a prefix list. A prefix lists is applied to incoming or outgoing routes. Those routes must meet the 
conditions of the prefix list; if not, FTOS drops the route. Prefix lists are globally applied on all interfaces 
running RIP. Configure the prefix list in the PREFIX LIST mode prior to assigning it to the RIP process. 

For configuration information on prefix lists, see 

Chapter 17, IP Access Control Lists, Prefix Lists, and 

Route-maps, on page 47

.

To apply prefix lists to incoming or outgoing RIP routes, use the following commands in the ROUTER 
RIP mode: 

In addition to filtering routes, you can add routes from other routing instances or protocols to the RIP 
process. With the 

 command syntax, you can include OSPF, static, or directly connected routes 

in the RIP process.

 

ROUTER RIP

Define a specific router to exchange RIP information 
between it and the Dell Force10 system.
You can use this command multiple times to exchange 
RIP information with as many RIP networks as you 
want.

 

ROUTER RIP

Disable a specific interface from sending or receiving 
RIP routing information.

 

 

ROUTER RIP

Assign a configured prefix list to all incoming 
RIP routes.

 

 

ROUTER RIP

Assign a configured prefix list to all outgoing 
RIP routes.
