ROUTE.CONF(5)             NetBSD File Formats Manual             ROUTE.CONF(5)


NAME

     route.conf -- static routes config file


DESCRIPTION

     The route.conf file is read by the staticroute rc.d script during system
     start-up and shutdown, and is intended for adding and removing static
     routes.

   FILE FORMAT
     Lines starting with a hash (`#') are comments and ignored.  Lines start-
     ing with a plus sign (`+') are run during start-up, while lines starting
     with a minus sign (`-') are run during system shutdown.  If a line starts
     with a `!', the rest of the line will get evaluated as a shell script
     fragment.  All other lines are passed to route(8).  During start-up, they
     are passed behind a ``route add -'' command and during shutdown behind a
     ``route delete -'' command.


FILES

     /etc/route.conf     The route.conf file resides in /etc.

     /etc/rc.d/staticroute
                         rc.d(8) script that parses route.conf.


EXAMPLES

     In this example, the interface for the desired routing changes is set,
     the IP address on that interface is determined, and a route is added dur-
     ing startup, or deleted during system shutdown.

           # Set interface and determine current IP address for added route.
           !ifname=bnx0
           !ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}')
           net 10.10.1 -interface ${ipaddr}

     In this example, IP forwarding is turned on during start-up, and a static
     route added for 192.168.2.0.  During system shutdown, the route is
     removed and IP forwarding turned off.

           # Turn on/off IP forwarding.
           +sysctl -w net.inet.ip.forwarding=1
           -sysctl -w net.inet.ip.forwarding=0
           net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
