Configuring BGP route reception filtering policies
You can use the following methods to configure BGP route reception filtering policies:
•
Use an ACL or prefix list to filter routing information received from all peers.
•
Use a routing policy, ACL, AS path list, or prefix list to filter routing information received from a
peer or peer group.
If you configure multiple filtering policies, apply them in the following sequence:
1. filter-policy import
2. peer filter-policy import
3. peer as-path-acl import
4. peer prefix-list import
5. peer route-policy import
Only routes passing all the configured policies can be received.
