did you try creating OSPF demand circuit over ISDN. This might work for you
too. But it will come up every time something in the OSPF domain changes,
and also every 30 minutes when LSAs refresh. This behavior actually changes
in 12.2 (CSCdp80470). Cisco is now using OSPF flooding reduction. Routers
don't send LSA refreshes anymore, all routes are marked as DNA. Neat stuff.
But I would still use Dialer Watch. Yes, you are right, the routes will
become reinstated over the ISDN link, but dialer watch is smart to
understand that. It will wait until those routes point to some other
interface (obviously with better metric), so then the route over ISDN will
disappear, and the ISDN will be brought down.
"If a valid route exists for at least one of the defined IP addresses, and
if the route is pointing to an interface other than the backup interface
configured for Dialer Watch, the primary link is considered up"
I hope this helps.
