Step 5
RP/0/RP0/CPU0:router(config)#
Enters a name for the OSPF process.
router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
Step 6
Configures an area for the OSPF process.
area area-id

Step 8
RP/0/RP0/CPU0:router(config-ospf)#
Sets the MPLS-TE loopback interface.
mpls traffic-eng router-id ip-address
Example:
