You brought up an xxcellent thought provoking point. My reply to your
question would be as under :-
ip ospf demand circuit :
Primal aim is to prevent the ospf's hello's from bring up a ddr link.
dialer-watch.
primal aim is to 'watch' a user defined set of routes and provide an
alternate path
I think, that when we have a 'grey' solution like this, it might be best to
see it from Cisco;s point of view and WHY they brought in a type of solution
to addres what TYPE of problem.
My guess is that the proctor would think likewise !
Just my 2 cents !!
