Configuring OSPF to Filter the Routes to Be Advertised

Configuring OSPF to Filter the Routes to Be Advertised


  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF process view is displayed.

  3. Run filter-policy { acl-number | acl-name acl-name | ip-prefix ip-prefix-name | route-policy route-policy-name } export [ protocol [ process-id ] ]

    OSPF is configured to filter the routes imported through the import-route command. Only the routes that pass the filtering criteria are advertised.

    • The parameter acl-number specifies the number of a basic ACL.
    • The parameter acl-name acl-name specifies the name of an ACL.
    • The parameter ip-prefix ip-prefix-name specifies the name of an IP prefix list.
    • The parameter route-policy route-policy-name specifies the name of a route policy.

    To filter the routes of a specific routing protocol or OSPF process, specify the parameter protocol [ process-id ]. If this parameter is not specified, OSPF filters all the imported routes.

    • The import-route command cannot be used to import external default routes.
    • OSPF filters the imported routes and generates Type 5 LSAs to advertise only external routes that pass the filtering criteria.
