+.SH DESCRIPTION
|
|
|
049c96 |
+Match packets based on routing table entries. This filter centers around the
|
|
|
049c96 |
+possibility to assign a
|
|
|
049c96 |
+.B realm
|
|
|
049c96 |
+to routing table entries. For any packet to be classified by this filter, a
|
|
|
049c96 |
+routing table lookup is performed and the returned
|
|
|
049c96 |
+.B realm
|
|
|
049c96 |
+is used to decide on whether the packet is a match or not.
|
|
|

|
049c96 |
+.TP
|
|

|
|

|
049c96 |
+.TP
|
|
|
049c96 |
+.BI classid " CLASSID"
|
|
|
049c96 |
+Push matching packets into the class identified by

|
|
049c96 |
+.IR CLASSID .

|

049c96 |
+Match if normal (i.e., destination) routing returns the given

049c96 |

|
|
|
049c96 |
+.SH EXAMPLES
|
|
|
049c96 |
+Consider the subnet 192.168.2.0/24 being attached to eth0:
|
|
|
049c96 |
+
|
|
|
049c96 |
+.RS
|
|
|
049c96 |
+.EX
|
|
|
049c96 |
+ip route add 192.168.2.0/24 dev eth0 realm 2
|
|
|
049c96 |
+.EE
|
|
|
049c96 |
+.RE
|
|
|
049c96 |
+
|
|
|
049c96 |
+The following
|
|
|
049c96 |
+.B route
|
|
|
049c96 |
+filter will then match packets from that subnet:
|
|
|
049c96 |
+
|
|
|
049c96 |
+.RS
|
|
|
049c96 |
+.EX
|
|
|
049c96 |
+tc filter add ... route from 2 classid 1:2
|
|
|
049c96 |
+.EE
|
|
|
049c96 |
+.RE
|
|
|
049c96 |
+
|
|
|
049c96 |
+and pass packets on to class 1:2.
|
|
|
049c96 |
+.SH NOTES
|
|
|
049c96 |
+Due to implementation details,
|
|
|
049c96 |
+.B realm
|
|
|
049c96 |
+values must be in a range from 0 to 255, inclusive. Alternatively, a verbose
|
|
|
049c96 |
+name defined in /etc/iproute2/rt_realms may be given instead.
