Configuring Route Map Redistribution

It is possible to learn and advertise IPv6 routes between different protocols. Such a process is referred to
as route redistribution and is configured using the
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 receiving network. In addition a route map may 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 ipv6 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
on page 17-24.
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:
ip route-map action ...
permit
deny
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
