Do this with Dialer profile. and give the IP to dialer profile. There is no
way that this will not work with it.
AS IT IS ALL ABOUT SPOOFING....... think about it.
if this interface that is dialer profile is down then ospf will belivee that
there is no topology change... and do u
know dialer interface never ever gets down it just spoof to be up..... that
is game.
