Configuring OSPFv3 Virtual Links

Context

After an OSPFv3 area is defined, OSPFv3 route updates between non-backbone areas are implemented through a backbone area. OSPFv3 requires all non-backbone areas to maintain connectivity with the backbone area and the backbone area to maintain its own connectivity as well. If this requirement cannot be met, configure OSPFv3 virtual links.

A virtual link must be configured at both ends of the link, or it will not take effect.

Perform the following operations on the switch that runs OSPFv3.

Procedure

Run system-view
The system view is displayed.
Run ospfv3 [ process-id ]

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 } | ipsec sa sa-name } ] ^*
A virtual link is created and configured.
