Have a rough idea of how to go about this but not 100% positive yet.
So we have a multi-area OSPF environment currently. We have been
tasked with adding a coop site into the mix that is physically
located off one of the ABR's. This coop is obviously for failover should
something happen to the current area 0. That being said I would think
the coop would need to be area 0 also in order to keep the communication
going in the event of failure at the original area 0. In order to do this I
was thinking maybe a virtual-link to connect the area 0's so that the
coop area 0 would still receive all required routing updates. I imagine
their would also have to be some routing policies put into place also
to keep traffic from traversing the coop area 0 unless a failover has occurred.
Am I on the right path or is my mind way out in left field.
