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

Route classifier in tc(8)                                              Linux                                             Route classifier in tc(8)

NAME

       route - route traffic control filter

SYNOPSIS

       tc filter ... route [ from REALM | fromif TAG ] [ to REALM ] [ classid CLASSID ] [ action ACTION_SPEC ]

DESCRIPTION

       Match  packets  based  on routing table entries. This filter centers around the possibility to assign a realm to routing table entries. For
       any packet to be classified by this filter, a routing table lookup is performed and the returned realm is used to  decide  on  whether  the
       packet is a match or not.

OPTIONS

       action ACTION_SPEC
              Apply an action from the generic actions framework on matching packets.

       classid CLASSID
              Push matching packets into the class identified by CLASSID.

       from REALM
       fromif TAG
              Perform source route lookups.  TAG is the name of an interface which must be present on the system at the time of tc invocation.

       to REALM
              Match if normal (i.e., destination) routing returns the given REALM.

EXAMPLES

       Consider the subnet 192.168.2.0/24 being attached to eth0:

              ip route add 192.168.2.0/24 dev eth0 realm 2

       The following route filter will then match packets from that subnet:

              tc filter add ... route from 2 classid 1:2

       and pass packets on to class 1:2.

NOTES

       Due  to  implementation  details,  realm  values  must  be  in  a  range from 0 to 255, inclusive. Alternatively, a verbose name defined in
       /etc/iproute2/rt_realms may be given instead.
