DETAILED STEPS

Command or Action Purpose

Step1 configure

Example:

RP/0/RP0/CPU0:router# configure

Enters global configuration mode.

Step2 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.

Step3 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.

Step4 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.

Step5 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.
