DETAILED STEPS
Command or Action
Step 1
configure
Step 2 router ospf process-name
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
Step 3 vrf vrf-name
Example:
RP/0/RSP0/CPU0:router(config-ospf)# vrf vrf1
Step 4
router-id { router-id }
Example:
RP/0/RSP0/CPU0:router(config-ospf-vrf)# router-id 192.168.4.3
Step 5 redistribute protocol [ process-id ] { level-1 | level-1-2 | level-2 }
[ metric metric-value ] [ metric-type type-value ] [ match { external
[ 1 | 2 ] }] [ tag tag-value ] route-policy policy-name]

Purpose
Enables OSPF routing for the specified routing
process and places the router in router
configuration mode.
The process-name argument is any
Note
alphanumeric string no longer than 40
characters.
Creates a VRF instance and enters VRF
configuration mode.
Configures a router ID for the OSPF process.
We recommend using a stable IPv4
Note
address as the router ID.
Redistributes OSPF routes from one routing
domain to another routing domain.
• This command causes the router to become
an ASBR by definition.
