Defining Route Maps
Route maps establish the conditions for redistributing routes from one routing
protocol to another, and for advertising and learning routes from one router to another.
A route map consists of
route-map commands, match statements that define the
conditions that a route must meet, and set statements that define the conditions that
apply to a route.
Creating a Route Map
Use the route-map command in Global Configuration mode to define a route map:
MOT (config)#
route-map <
WORD>
[ permit | deny ] <
0-65535
>
where:
WORD
is the name that uniquely identifies an instance of a route map; instances
with lower sequence numbers are parsed first.
permit specifies perform set operations, if the match conditions are met.
deny specifies deny set operations.
0-65535
identifies an instance of the route map.
Once the route map is created using the route-map command, you enter Route Map
Configuration mode. Refer to the following sections to define parameters for your
route map.
Using Match Statements to Define Routing Conditions
Match statements define the conditions that a route must meet. Each instance may
contain multiple match statements. If all match statements in an instance match for a
given route, the route meets the conditions of the instance. The order of match
statements within an instance is not relevant. If an instance contains no match
statements, all routes meet the conditions of the instance, however, they can be denied
by an instance with a lower sequence number.
Follow these steps to define the conditions for a route:
1. Use the match as-path command in Route Map Configuration mode to match
one or more BGP AS-path access lists:
MOT (config-rmap)#
match as-path <
1-99
> <
100-199
> [...<
1-99
>
<
100-199
>]
where:
