This filter centers around the +possibility to assign a +.B realm +to routing table entries. For any packet to be classified by this filter, a +routing table lookup is performed and the returned +.B realm +is used to decide on whether the packet is a match or not. +.SH OPTIONS +.TP +.BI action " ACTION_SPEC" +Apply an action from the generic actions framework on matching packets. +.TP +.BI classid " CLASSID" +Push matching packets into the class identified by +.IR CLASSID . +.TP +.BI from " REALM" +.TQ +.BI fromif " TAG" +Perform source route lookups. +.I TAG +is the name of an interface which must be present on the system at the time of +.B tc +invocation. +.TP +.BI to " REALM" +Match if normal (i.e., destination) routing returns the given +.IR REALM . +.SH EXAMPLES +Consider the subnet 192.168.2.0/24 being attached to eth0: + +.RS +.EX +ip route add 192.168.2.0/24 dev eth0 realm 2 +.EE +.RE + +The following +.B route +filter will then match packets from that subnet: + +.RS +.EX +tc filter add ... route from 2 classid 1:2 +.EE +.RE + +and pass packets on to class 1:2. +.SH NOTES +Due to implementation details, +.B realm +values must be in a range from 0 to 255, inclusive.
