DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables OSPF routing for the specified routing process and
places the router in router configuration mode.
router ospf process-name
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
Step 2
The process-name argument is any alphanumeric
string no longer than 40 characters.
Note
Enters area configuration mode and configures a backbone
area.
area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area 0
Step 3
•
The area-id argument can be entered in dotted-decimal
or IPv4 address notation, such as area 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.
Enters interface configuration mode and associates one or
more interfaces to the area.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# interface
Serial 0/1/0/3
Step 4
Enters area configuration mode and configures an area used
for multiple area adjacency.
area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area 1
Step 5
•
The area-id argument can be entered in dotted-decimal
or IPv4 address notation, such as area 1000 or
area 0.0.3.232. However, you must choose one form or
the other for an area. We recommend using the IPv4
