Carrier Access none manual Ip ospf authentication, Message-digest, Null

Configuration - Ethernet Interface Mode

ip ospf authentication

Use the Ethernet Interface ip ospf authentication command to enable the authentication method (either message-digest or simple authentication) for this Ethernet interface. To remove the authentication type for this interface set the parameter to null or see no ip ospf authentication command on page 11-18.

Note: If an optional parameter is not entered, the authentication method of simple authentication is applied to the interface.

Syntax: (config-int-eth-{n})# ip ospf authentication [message-digestnull]

Field	Definition
message-digest	Optional parameter. Enables MD5 Authentication on the area.
null	Optional parameter. No authentication is used. Note: This is useful for
	overriding password or message-digest authentication if configured
	for an area.

Example: (config-int-eth-1)# ip ospf authentication message-digest

Note: The authentication key must be defined before this command is implemented.

Therefore if setting simple authentication:

Example: ip ospf authentication-key pass777

ip ospf authentication

Therefore if setting message-digest:

Example: ip ospf message-digest-key 1 md5 pass777

ip ospf authentication message-digest
