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

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" .TQ 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 .

Consider the subnet 192.168.2.0/24 being attached to eth0: The following route filter will then match packets from that subnet: and pass packets on to class 1:2. 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. tc (8), ip-route (8)
