Step8 message-digest-key key-id md5 {key | clear key
| encrypted key}
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-vl)#
message-digest-key 4 md5 yourkey
Defines an OSPF virtual link.
•See the “Virtual Link and Transit Area for OSPF”
section on page 180 to understand a virtual link.
•The key-id argument is a number in the range from 1 to
255. The key argument is an alphanumeric string of up
to 16 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.
Step9 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.

or
commit
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-vl)# end
or
RP/0/RP0/CPU0:router(config-ospf-ar-vl)# commit
Saves configuration changes.
•When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
•Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
Step1 1 show ospf [process-name] [area-id]
virtual-links
or
show ospfv3 [process-name] virtual-links
Example:
RP/0/RP0/CPU0:router# show ospf 1 2
virtual-links
or
RP/0/RP0/CPU0:router# show ospfv3 1
virtual-links
(Optional) Displays the parameters and the current state of
OSPF virtual links.
