Configuring a Route Policy
A route policy is used to filter routing information, and modify attributes of matching routing information.
The match criteria of a route policy can be configured by referencing filters above mentioned.
A route policy can comprise multiple nodes, and each route policy node contains:
z
if-match
clauses: Define the match criteria that routing information must satisfy. The matching
objects are some attributes of routing information.
z
apply
clauses: Specify the actions to be taken on routing information that has satisfied the match
criteria, such as route attribute modification.
Prerequisites
Before configuring this task, you need to configure:
