You have to have two virtual links. If you have two routers and there
are two paths through two different transit areas you will need to have
two virtual links between those two routers. One through each transit
area.
I always thought if you have authentication on OSPF area 0 then you need
to have that specified on the virtual-link because the virtual-link is
part of area 0, which has authentication. If you had to take off the
MD5 authentication from the virtual-link in order to get the
virtual-link to come up what is the purpose of the command on the
virtual-link.
I guess it must be YAIB (Yet Another IOS Bug).

Hi
This is a quick one. When I have 2 spokes that can act as ABRs between
area
1 and area 2 let's say, do I need 2 virtual links to area 0? Or should I
only have one virtual link that I choose?
Another question, if area 0 is authenticated then do I have to enable
authentication on the virtual link? I thought I should, but the only way
I'm
able to bring one of the virtual links up is to remove the md5
authentication!! Is there a problem because I'm using 2 parallel VLinks
or
this is the way it is supposed to work?
Thanks
Tarek
