route.conf
ROUTE.CONF(5) BSD 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 starting with a plus sign ('+') are run during start-up, while lines start-
ing 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 shut-
down 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
