This is bit of a trap I feel.. Have you got any networks on that router that
are not in IGRP, say for example one of the interfaces in only ospf? There
are some rules with the default network command, I can't remember them
correctly as it's late and I haven't got a clue what I'm talking about anyway
but something like, the default network you select cannot be already in IGRP
with the network command (IGRP will add a odd static route that you can't
kill with out a reload sometime) and the network you select must be connected
to the router that orginates the default network (has the default-network
command entered on it, in your case router A). Forget OSPF for now, see if
you can get the IGRP bit to work.
Hope this help but if it does I'd be surprised :-)
