tc-route(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.
