Filter incoming routes using an 
ACL or IP prefix list 

filter-policy { acl-number | 
ip-prefix ip-prefix-name } 
import 

Reference a route policy to 
routes from an IPv4 MBGP 
peer/peer group 

peer { group-name | 
ip-address } route-policy 
policy-name import 

Reference an ACL to filter 
routing information from an 
IPv4 MBGP peer/peer group 

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

Reference an AS path ACL to 
filter routing information from 
an IPv4 MBGP peer/peer group 

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

Reference an IP prefix list to 
filter routing information from 
an IPv4 MBGP peer/peer group 

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

At least one of these 
approaches is required. 

No inbound route filtering is 
configured by default. 

Specify the maximum number 
of routes that can be received 
from an IPv4 MBGP peer/peer 
group 

peer { group-name | 
ip-address } route-limit limit 
[ percentage ] 

Optional 

The number is unlimited by 
default. 

 

Members of a peer group can have different route reception filtering policies from the peer group. 

 

By configuring MBGP route dampening, you can suppress unstable routes from being added to the 

MBGP routing table or being advertised to MBGP peers. 

Follow these steps to configure BGP route dampening: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Enter IPv4 MBGP address 
family view 

— 

Configure BGP route 
dampening parameters

Required 

Not configured by default 

 

You can modify MBGP route attributes to affect route selection.
