NOTE: With the peer default-route-advertise command executed, the router sends a default route with the next 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: Step 1. Enter system view. 2. Enter BGP view. 3. Enter IPv4 MBGP address family view. Command system-view bgp as-number ipv4-family multicast Remarks N/A N/A 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 Use at least one command. or a peer group: peer { group-name | ip-address } filter-policy acl-number export By default, no outbound route filtering is configured. • 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 190
