OmniSwitch AOS Release 6 Network Configuration Guide

It is possible to configure the RIP protocol to advertise routes learned from other routing protocols into the 
RIP network. Such a process is referred to as route redistribution and is configured using the 

command.

Redistribution uses route maps to control how external routes are learned and distributed. A route map 
consists of one or more user-defined statements that can determine which routes are allowed or denied 
access to the RIP network. In addition a route map may also contain statements that modify route parame-
ters before they are redistributed. 

When a route map is created, it is given a name to identify the group of statements that it represents. This 
name is required by the ip redist command. Therefore, configuring route redistribution involves the 
following steps:

1 Create a route map, as described in 

.

2 Configure redistribution to apply a route map, as described in 

A route map specifies the criteria that are used to control redistribution of routes between protocols. Such 
criteria is defined by configuring route map statements. There are three different types of statements: 

• Action. An action statement configures the route map name, sequence number, and whether or not 

redistribution is permitted or denied based on route map criteria. 

• Match. A match statement specifies criteria that a route must match. When a match occurs, then the 

action statement is applied to the route. 

• Set. A set statement is used to modify route information before the route is redistributed into the 

receiving protocol. This statement is only applied if all the criteria of the route map is met and the 
action permits redistribution.

The ip route-map command is used to configure route map statements and provides the following action, 
match, and set parameters:

Refer to the “IP Commands” chapter in the OmniSwitch CLI Reference Guide for more information about 
the ip route-map command parameters and usage guidelines.

Once a route map is created, it is then applied using the 

 for more information.
