Introduction to Route Policy
Route Policy
A route policy is used on a router for route filtering and attributes modification when routes are received,
advertised, or redistributed.
To configure a route policy, you need to define some filters based on the attributes of routing information,
such as destination address, advertising router's address and so on. The filters can be set beforehand
and then applied to the route policy.

Filters

There are six types of filters: ACL, IP prefix list, and route policy.
ACL
ACL involves IPv4 ACL and IPv6 ACL. An ACL is configured to match the destinations or next hops of
routing information.
For ACL configuration, refer to ACL configuration in the Security Volume.
IP prefix list
IP prefix list involves IPv4 and IPv6 prefix list.
