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 route policy to 
advertisements to an IPv4 
MBGP peer/peer group 

peer { group-name | 
peer-address } route-policy 
route-policy-name export 

Reference an ACL to filter 
advertisements to an IPv4 
MBGP peer/peer group 

peer { group-name | 
ip-address } filter-policy 
acl-number export 

Reference an AS path ACL to 
filer route advertisements to an 
IPv4 MBGP peer/peer group 

peer { group-name | 
ip-address } as-path-acl 
as-path-acl-number export 

Reference an IP prefix list to 
filer route advertisements to an 
IPv4 MBGP peer/peer group 

peer { group-name | 
ip-address } ip-prefix 
ip-prefix-name export 

At least one of these 
approaches is required.  No 
outbound route filtering is 
configured by default 

 

By configuring MBGP route reception filtering policies, you can filter out unqualified routes from an 

MBGP peer or peer group. 

If several filtering policies are configured, they are applied in the following sequence: 

z 

z 

z 

z 

z 

Only the routes that have passed all the configured policies can be advertised.
