	I am trying to set up my FreeBSD laptop, so that it can connect to
	multiple networks and/or also call my home network via ppp. I have the
	ppp conection working as far as getting the link up, but I am strugling
	with routing. 

	When the machine boots the folowing perl script is escruted:


#!/usr/local/bin/perl

%gateway = ('205.159.77.233' =>	{
									gw	=> '205.159.77.234',
									dns	=> ['205.159.77.240',
											'208.140.99.9',
											'198.81.225.1'],
									dom => 'fas.com',
									yp => 'yes"
								},
			'222.198.37.141' =>	{
									gw	=> '222.198.37.254',
									dns	=> ['192.1.37.20'],
									dom	=> 'westvaco.com',
									yp => 'no"
								},
			'192.168.0.3 -link0' =>	{
									gw	=> '192.168.0.1',
									dns	=> ['192.168.0.1'],
									dom	=> 'westvaco.com',
									yp => 'no"
								},
);

`route delete default 2>&1 > /dev/null`;

foreach $key (keys(%gateway))
{
	$thiskey = $key;
	$up=1;
	`ifconfig ep0 inet $key netmask 0xffffff00`;
	unless (system("ping -c 1 $gateway{$key}{gw} > /dev/null"))
	{
		last;
	}
	print "Cannot ping $gateway{$key}{gw}\n";
	$up=0;
}

if($up)
{
	`route add default $gateway{$thiskey}{gw}`;
	 open RESOLVFILE, "> /etc/resolv.conf";
	 print RESOLVFILE "domain $gateway{$thiskey}{dom}\n";
	 foreach $ipnum (@{$gateway{$thiskey}{dns}})
	 {
 		print RESOLVFILE "nameserver $ipnum\n";
	 }
	 close RESOLVFILE;
	print "Configured for network $gateway{$thiskey}{dom}\n";
}
else
{
	print "Cannot find a known network\n";
	`/usr/bin/killall ypbind`;
}

	Now here is the problem. If the machine is *not* conectedd to any of
	these networks, I still get the folowing routing table:

	Now as you can see, I have some pretty strange entries her. For each
	one of the networks that I tride I have this mysterios link#5 entry.
	route delete refuses to remove these entries. I also have a network
	entry for the last network that I tried.

	What are these entries, and how do I avoid creating them, or dlete them
	after I test for that network ?

	Thanks.
