Pavlin,
	This is probably more work than you need to do and it doesn't
solve the problem of your default being deleted when xorp exits if xorp
installed it for you.

	Can you just add a flag to any route that says not to delete it
when xorp exits no matter what the state was before xorp started?

Thanks,
Tom
