This command takes effect only on
the ABR/ASBR of an NSSA or
totally NSSA area.
Configuring an OSPFv3 virtual link
You can configure a virtual link to maintain connectivity between a non-backbone area and the
backbone, or in the backbone itself.
Both ends of a virtual link are ABRs that must be configured with the vlink-peer command.
• Do not configure virtual links in the areas of a GR-capable process.
To configure a virtual link:
1. Enter system view.
system-view
N/A
2. Enter OSPFv3 view.

Configuring OSPFv3 network types
By the link layer protocol, OSPFv3 classifies networks into different types, including broadcast,
NBMA, P2MP, and P2P. By default, OSPFv3 considers the network type as broadcast.
