Hi All, R4(config-if)#ip ospf authentication ? message-digest Use message-digest authentication null Use no authentication <cr>
What does this “null” really mean? If it’s no authentication, then is there any need of wasting time coming all the way to configure authentication and you just leave it at “null”? Isn't better to leave it without any authentication? or what does it really refer to here?
