Control Rip Routing Updates - Dell Force10 Z9000 Configuration Manual

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:
Command Syntax
neighbor ip-address
passive-interface interface
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
Route-maps, on page
To apply prefix lists to incoming or outgoing RIP routes, use the following commands in the ROUTER
RIP mode:
Command Syntax
distribute-list prefix-list-name in
distribute-list prefix-list-name out
In addition to filtering routes, you can add routes from other routing instances or protocols to the RIP
process. With the

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

RIP routes.
ROUTER RIP Assign a configured prefix list to all outgoing
RIP routes.
