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 starting 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 during 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
