Configuring An Ospfv3 Virtual Link - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

To configure an NSSA area, configure the nssa command on all the routers attached to the area.
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.
