Two things that are not clearly documented are

	1.  dump-routes only works with dynamic routing, and we 
		only currently have DV in there (if someone wants
		to donate their LS code, we'd shamelessly 
		purloin it...hint, hint :-)
	2.  dump-routes only works after you issue the ``$ns run''
		command, because it is that command that sets up
		all the rtObject instances.

If you are using dynamic routing, then try the following code:

	proc my-dump-routes {node fh} {
		set dr [$node rtObject?]
		$dr dump-routes $fh
	}
	$ns at 0.0 "my-dump-routes $node $fh"
	$ns run

and see if it works,
