ith the peer default-route-advertise command executed, the router sends a default route with the nex
hop as itself to the specified MBGP peer or peer group, whether the default route is available or not in the
routing table.
Configuring outbound MBGP route filtering
If several filtering policies are configured, they are applied in the following sequence:
1. filter-policy export
2. peer filter-policy export
3. peer as-path-acl export
4. peer ip-prefix export
5. peer route-policy export
Only the routes that have passed all the configured policies can be advertised.
To configure BGP route distribution filtering policies:
Ste
Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Enter IPv4 MBGP address
family view.
ipv4-family multicast N/A
4. Configure BGP route
distribution filtering policies.
• Configure the filtering of redistributed
routes:
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ direct | 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
Use at least one command.
By default, no outbound
route filtering is configured.
