freebsd stable - Dec 2007 - /etc/rc.d/netif wont add default gateway

hi!

whenever i run /etc/rc.d/netif it will read rc.conf and add the pc IP and
netmask but it wont read the default gateway resulting lost connectivity to
internet

# -- my /etc/rc.conf :

***my question is, why /etc/rc.d/netif wont read directly from my
/etc/rc.conf as I already stated the defaultrouter="192.168.1.1"
there?

i'm on FreeBSD 6.2 on LAN

[root@msc ~]$ uname -a
FreeBSD www.msc.edu 6.3-PRERELEASE FreeBSD 6.3-PRERELEASE #1: Sat Dec  1
14:31:02 MYT 2007     root@msc.edu:/usr/obj/usr/src/sys/MSC  i386
[root@msc~]$

thanks for helping

what happens is that "/etc/rc.d/netif restart" first runs
"/etc/rc.d/netif stop". This stops all network interfaces.
Now the kernel routing system gets notified that these interfaces 
are no longer available and deletes all routes that use this
interfaces.
After that "/etc/rc.d/netif start" runs and the interfaces
become available again. Every time a network interface becomes
available, the kernel adds a route to the immedialtely connected
network (which is determined by interface address and netmask).

So stopping an interface has the side effect of clearing ALL routes
going through this nterface, while starting an interface has only
the side effect of adding a route for the net that is locally
connected to this interface.
The kernel can not add the default route on its own again because
all information about this route had been deleted ehrn the interface
went down.

To add non-local routes (including the default route) you could now
run "/etc/rc.d/routing start"
