OK all, you are absolutely correct about the fact that I would end up
reading a lot and learing much about this topic while trying to solve my
issue. The good news is that yes I think you pointed out very useful points
that will likely come handy when troubleshooting this kind of thing. Thank
you.

The other good news is that it works now!

The not-so-good news is that I cannot tell you how I got it to work. I
reached a point where I was removing things and putting them back on.
Honestly I think I ended up with the same configuration, because I had
already applied all of the required precautions for demand circuits when
they're touching RIP/IGRP! I do believe it was an IOS issue where the demand
circuit was "refusing" to deliver! (Or at least I'd like to think so at this
stage before the lab :)

Thanks again for your help and your support.
Tarek

Try it without specifying the network type, ip ospf cost 9999 on both sides,
leave the hello interval at the default. From there, I would suggest
bringing the config down to basic OSPF, no authentication, area ranges, or
summary addresses. That way you can start adding things one by one and find
the command that introduces the instability.

~Jim, Guy and all,
~
~Here .. I removed the dialer profile, removed IGRP, and
~basically removed
~almost every freaking thing.
~
~The multicast going from my BRI as source kicks in once the
~circuit goes
~down :(

~Thanks
