Dear All, I need to setup different route with different tos value. I can use the flowing command to add a tos route to routing table. ip route 192.168.0.2/32 via 192.168.0.1 tos 0x1c and ip route 192.168.0.2/32 via 192.168.0.1 tos 0x40 I used "ping -Q" to test it with different tos, the output packet is marked correctly. The problem that is only the tos value defined at /etc/iproute/rt_dsfield can route base on the tos route. tos 0x1c work but 0x40 not work. Do any one know why? Thank you! -- Regards, Michael Chung Pui Kei Computer Engineering Year 3 School of Engineering Hong Kong University of Science and Technology Email Address: eg_cpkaa@xxxxxxxxxx _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
