I have set-up a virtual link with MD5 authentication. Then I decided to try whether the authentication really works, so I have put different password on one end of the VL. To my surprise, virtual link gets established even when password do not match -- and in fact even when authentication config is missing completely on one end of the link. Config is as follows:
area 5 virtual-link xx.x.0.1 authentication message-digest
area 5 virtual-link xx.x.0.1 message-digest-key 1 md5 annular2
area 5 virtual-link xx.x.0.12 authentication message-digest
area 5 virtual-link xx.x.0.12 message-digest-key 1 md5 annular
MD5 authentication is enabled in area 0 (as required by UniverCD documentation -- funny, as this is not mentioned in Parkhurst's OSPF handbook).
