Hello all..
I have two routers running ospf with R2 part of Area 0 & 1 and R1 part of
Area 1 & 5. So I have a virtual-link running between these two routers. It
works well that way. Now when I enabled authentication on only one router,
R1, virtual link still remains up and all there are no missing routes or
neighbors. I was expecting R1 to tear down neighbor relationship with R2,
but nothing of that sort happens. But when I give debug ip ospf adj command,
it shows authentication failure. All works well otherwise even if I don't
enable authentication on R2. Any clues??
Already tried rebooting routers.
Thanks
Devin
