     NAME
          route - route traffic control filter

     SYNOPSIS
          tc filter ... route [ 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 fil-
          ter, 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 sys-
               tem 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
