Configuring An Ospfv3 Virtual Link; Configuring Ospfv3 Network Types - HP HPE FlexNetwork 7500 series Configuration Manual

To configure a totally NSSA area, configure the nssa no-summary command on the ABR. The ABR
of a totally NSSA area does not advertise inter-area routes into the area.
To configure an NSSA area:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enter OSPFv3 area view.
4. Configure the area as an
NSSA area.
5. (Optional.) Set a cost for
the default route advertised
to the 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.
IMPORTANT:
• 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:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enter OSPFv3 area view.
4. Configure a virtual link.

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.
