DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Identifies the OSPF routing process and enters OSPF
configuration mode.
router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 109
Step 2
(Optional)
Specifies the non-default VRF.
vrf vrf-name
Example:
RP/0/RP0/CPU0:router(config-ospf)# vrf red
Step 3
Disables LDP IGP synchronization on an interface.Use one of the following commands:
Step 4
•
area area-id mpls ldp sync disable
•
area area-id interface name mpls ldp sync disable
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 1 mpls ldp
sync disable
RP/0/RP0/CPU0:router(config-ospf)# area 1 interface
POS 0/2/0/0 mpls ldp sync disable
(Optional)
