characters. The routers at both ends of the
virtual link must have the same key identifier
and key to be able to route OSPF traffic.
•
The authentication-key key command is
not supported for OSPFv3.
•
Once the key is encrypted it must remain
encrypted.
—
Repeat all of the steps in this task on the ABR that is at the other end
of the virtual link. Specify the same key ID and key that you specified
for the virtual link on this router.

Step 10
(Optional) Displays the parameters and the current
state of OSPF virtual links.
Do one of the following:
Step 11
•
show ospf [ process-name ] [ area-id ] virtual-links
•
show ospfv3 [ process-name ] virtual-links
Example:
RP/0/RSP0/CPU0:router# show ospf 1 2 virtual-links
or
RP/0/RSP0/CPU0:router# show ospfv3 1 virtual-links
Examples
In the following example, the show ospfv3 virtual links EXEC configuration command verifies that the
OSPF_VL0 virtual link to the OSPFv3 neighbor is up, the ID of the virtual link interface is 2, and the IPv6
address of the virtual link endpoint is 2003:3000::1.
