Purpose
Command or Action
Enables OSPFv3 routing for the specified routing process
and places the router in router ospfv3 configuration mode.
•
router ospfv3 process-name
Example:
The
process-name
argument is any
alphanumeric string no longer than 40
characters.
Note
RP/0//CPU0:router(config)# router ospf 1
or
RP/0//CPU0:router(config)# router ospfv3 1
Configures a router ID for the OSPF process.
router-id
{
router-id
}
Step 4
Example:
We recommend using a stable IPv4 address as
the router ID.
Note
RP/0//CPU0:router(config-ospf)# router-id
192.168.4.3
Enters area configuration mode and configures a
nonbackbone area for the OSPF process.
area area-id
Example:
Step 5
• The
area-id
argument can be entered in
dotted-decimal or IPv4 address notation, such as area
RP/0//CPU0:router(config-ospf)# area 1
1000 or area 0.0.3.232. However, you must choose
one form or the other for an area. We recommend
using the IPv4 address notation.
Defines an OSPF virtual link.
virtual-link router-id
Step 6
Example:
• See .
RRP/0//CPU0:router(config-ospf-ar)# virtual-link
10.3.4.5
Selects MD5 authentication for this virtual link.
authentication message-digest
Example:
Step 7
RP/0//CPU0:router(config-ospf-ar-vl)#authentication
message-digest
Defines an OSPF virtual link.
message-digest-key key-id md5
{
key
|
clear key
|
encrypted key
}
Step 8
• See to understand a virtual link.
Example:
• The
key-id
argument is a number in the range from
1 to 255. The
key
argument is an alphanumeric string
RP/0//CPU0:router(config-ospf-ar-vl)#message-digest-key
4 md5 yourkey
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.
