• Configure the filtering of redistributed
routes:
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ direct | isis
process-id | ospf process-id | rip
process-id | static ]
• Apply a routing policy to
advertisements to an IPv4 MBGP peer
or a peer group:
peer { group-name | peer-address }
route-policy route-policy-name export
• Reference an ACL to filter
advertisements to an IPv4 MBGP peer
or a peer group:
peer { group-name | ip-address }
filter-policy acl-number export
• Reference an AS path list to filter route
advertisements to an IPv4 MBGP peer
or a peer group:
peer { group-name | ip-address }
as-path-acl as-path-acl-number export
• Reference an IP prefix list to filter route
advertisements to an IPv4 MBGP peer
or a peer group:
peer { group-name | ip-address }
ip-prefix ip-prefix-name export

Configuring inbound MBGP route filtering
By configuring MBGP route reception filtering policies, you can filter out unqualified routes from an
MBGP peer or peer group. Members of a peer group can have different route reception filtering policies
from the peer group.
If several filtering policies are configured, they are applied in the following sequence:
1. filter-policy import
2. peer filter-policy import
3. peer as-path-acl import
4. peer ip-prefix import
5. peer route-policy import
Only the routes that have passed all the configured policies can be advertised.
