3. Configuring BGP route reception filtering policies
You can use the following methods to configure BGP route reception filtering policies:
• Use ACL or IP prefix list to filter routing information received by all peers.
• Use routing policy, ACL, AS-path ACL, or IP prefix list to filter routing information received by the
specified peer or peer group.
If several filtering policies are configured, they are applied in the following sequence:
• filter-policy import
• peer filter-policy import
• peer as-path-acl import
• peer ip-prefix import
• peer route-policy import
Only routes passing all the configured policies can be received.
