фильтр управления движением по маршруту (route traffic control filter)
Имя (Name)
route - route traffic control filter
Синопсис (Synopsis)
tc filter ... route [ from REALM | fromif TAG ] [ to REALM ] [
classid CLASSID ] [ action ACTION_SPEC ]
Описание (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.
Параметры (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.
Примеры (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.
Примечание (Note)
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.
