Enabling OSPF on a Multi-Area Adjacency Interface

Procedure

1. Run system-view

   The system view is displayed.

2. Run ospf [ process-id | router-id router-id ] ^*

   An OSPF process is started, and the OSPF view is displayed.

3. Run area area-id

   The OSPF area view is displayed.

4. Enable OSPF on an interface.
   1. Run twice quit

      The system view is displayed.

   2. Run interface interface-type interface-number

      The interface view is displayed.

   3. Run ospf enable [ process-id ] area area-id

      OSPF is enabled on the interface.

5. Run ospf enable multi-area area-id

   OSPF is enabled on the multi-area adjacency interface.

6. Run ospf mtu-enable multi-area area-id

   The multi-area adjacency interface is configured to add its actual MTU in DD packets to be sent and check whether the MTU in a received DD packet is greater than the local MTU.

   

   If the MTU in DD packets is changed, neighbor relationships will be reestablished.

7. Run commit

   The configuration is committed.
