• The authentication-key key command is not supported for OSPFv3.
• Once the key is encrypted it must remain encrypted.
Step 9 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 11 Do one of the following:
• show ospf [ process-name ] [ area-id ] virtual-links
• show ospfv3 [ process-name ] virtual-links
Example:
RP/0//CPU0:router# show ospf 1 2 virtual-links
or
RP/0//CPU0:router# show ospfv3 1 virtual-links
(Optional) Displays the parameters and the current state of OSPF virtual links.

ABR 1 Configuration
ABR 2 Configuration
In the following example, the show ospfv3 virtual links 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.
