Configuring OSPF to Filter the Routes to Be Advertised

Configuring OSPF to Filter the Routes to Be Advertised

Procedure

  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 } 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.

    You can specify the parameter protocol [ process-id ] to filter the routes of a certain routing protocol or a certain OSPF process. If the parameter protocol [ process-id ] is not specified, OSPF filters all imported routes.

    NOTE:
    • The import-route command cannot be used to import external default routes.
    • Only the external routes that passing the filtering criteria are advertised through Type 5 LSAs generated by OSPF.

  4. Run commit

    The configuration is committed.
