address message-digest-key md5

Description: 

Enables OSPF MD5 authentication and configures the MD5 key. The no version deletes an MD5 key.

NOTE: If all the MD5 keys have been deleted, the authentication type is still MD5, but you need to configure MD5 keys. NOTE: To disable MD5 authentication for the interface, use the address authentication-none command. NOTE: You must issue the address area command before issuing this command.

Syntax: 

address { ipAddress | unnumbered interfaceType interfaceSpecifier }
message-digest-key keyID md5 [ 0 | 8 ] msgDigestKey

no address { ipAddress | unnumbered interfaceType interfaceSpecifier }
message-digest-key keyID
