Thanks to everyone who chipped in your view. You
guys/gals are so wonderful!
I'm summarizing the situation:
With both the physical area 0 router and Virtual
linked remote router having "area 0 authen mess", the
virtual links are up and authenticated, but with Null
key, which might not satisfy the lab requirement. I do
see links being fully exchanged.
How about loopbacks? All those loopback interfaces I
am supposed to put inside area 0, do I really need to
apply the "ip ospf mess 1 md5 <key>", per possible lab
requirement?
Thanks,
Frank
