Precedence
You can set a priority to a route map by specifying a precedence value with the following command:
The lower the value, the higher the precedence. If two route maps have the same precedence value,
the lower number has higher precedence.
Configuration Overview
To configure route maps
1. Define the network filter.
Enter a filter number from 1 to 256. Specify the IP address and subnet mask of the network that
you want to match. Enable the network filter. You can distribute up to 256 network filters among
32 route maps each containing eight access lists.
2. Optionally, define the criteria for the access list and enable it.
Specify the access list and associate the network filter number configured in
.
This step and
are optional, depending on the criteria that you want to match. In this step,
the network filter number is used to match the subnets defined in the network filter. In
the autonomous system number is used to match the subnets. Alternately, you can use both
and
criteria (access list [network filter] and access path [AS filter]) to configure
the route maps.
3. Optionally, configure the attributes in the AS filter menu.
