Configuring RIP Configuring Redistribution
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 19-12
Configuring Redistribution
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 ip redist
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 can also contain statements that modify route
parameters 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 “Using Route Maps” on page 19-12.
2 Configure redistribution to apply a route map, as described in “Configuring Route Map Redistribution”
on page 19-15.
Using Route Maps
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 AOS Release 8 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 ip redist command. See “Configuring Route Map
Redistribution” on page 19-15 for more information.
