Configuring OSPFv3 Virtual Links
Context
After OSPFv3 areas are defined, OSPFv3 route update between non-backbone areas is implemented through a backbone area. Then, OSPFv3 requires that all non-backbone areas should maintain the connectivity with the backbone area and the backbone area should maintain its own connectivity. In actual applications, this requirement may not be met because of some restrictions. To solve this problem, you can configure OSPFv3 virtual links.
A virtual link must be configured at both ends of the link; otherwise, it does not take effect.
Do as follows on the router that runs OSPFv3.
Procedure
- Run system-view
The system view is displayed.
- Run ospfv3 [ process-id ]
The OSPFv3 view is displayed.
- Run area area-id
The OSPFv3 area view is displayed.
- Run vlink-peer router-id [ hello hello-interval | retransmit retransmit-interval | trans-delay trans-delay-interval | dead dead-interval | instance instance-id | authentication-mode { hmac-sha256 key-id key-id { plain plain-text | [ cipher ] cipher-text } | keychain keychain-name } ] *
A virtual link is created and configured.
