DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router ospf
process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
Enables OSPF routing for the specified routing process, and
places the router in router configuration mode.
Note The process-name argument is any alphanumeric
string no longer than 40 characters.
Step 3
router-id {
ipv4-address
|
interface-type
interface-instance
}
Example:
RP/0/RP0/CPU0:router(config-ospf)# router-id
192.168.4.3
Configures a router ID for the OSPF process.
Step 4
authentication [message-digest | null]
Example:
RP/0/RP0/CPU0:router(config-ospf)#
authentication message-digest
Enables MD5 authentication for the OSPF process.
• This authentication type applies to the entire router
process unless overridden by a lower hierarchical level
such as the area or interface.
Step 5
message-digest-key
key-id
md5 {
key
| clear
key
| encrypted
key
}
Example:
RP/0/RP0/CPU0:router(config-ospf)#
message-digest-key 4 md5 yourkey
Specifies the MD5 authentication key for the OSPF process.
• The neighbor routers must have the same key identifier.
