A route policy is applied on a router to filter routes when they are received, advertised or redistributed 

and to modify some attributes of permitted routes. 

Complete the following tasks to configure a route policy: 

Defining Filters 

Defining an Extended Community List 

Creating a Route Policy  

 

Before configuring this task, you need to decide on: 

z 

IP-prefix list name 

z 

Matching address range 

z 

Extcommunity list sequence number 

Identified by name, an IPv4 prefix list can comprise multiple items. Each item specifies a prefix range to 

match and is identified by an index number.  

An item with a smaller index number is matched first. If one item is matched, the IP prefix list is passed, 

and the routing information will not go to the next item. 

Follow these steps to define an IPv4 prefix list:
