Re: Stubborn router.

Yes only on the hub router. Entered the commands and checked with "show
ip ospf nei" but it showed no neighbor entries (no lines, regardless of
adj state). Deleted the two neighbor config lines (or at least tried
to) and re-entered the same commands and the neighbors are then
recognised, forming full adjacencies. I then had duplicate lines in the
config for each neighbor.

The router allowed me to remove the duplicate entries, but the original
two lines could not be removed. I reloaded a few minutes after it
happened and it has been fine since, but just thought it was an
interesting bug.
