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 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 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.
