Hi list, I have tried google but just cant get this to work or figure it out. My setup ======== vanilla 2.6.13 kernel with CONFIG_IP_ROUTE_MULTIPATH=y CONFIG_IP_ROUTE_MULTIPATH_CACHED=y CONFIG_IP_ROUTE_MULTIPATH_RR=y CONFIG_IP_ROUTE_MULTIPATH_RANDOM=y CONFIG_IP_ROUTE_MULTIPATH_WRANDOM=y CONFIG_IP_ROUTE_MULTIPATH_DRR=y My configuration: A host with two ppp links. Ontop of these two ppp dialup links i have created two CIPE tunnels, one on each link. Both A and B are under my control. +----+ cipcb0/ppp0 +-----+ | |----------------------| | | A | | B | | | cipcb1/ppp1 | | | |----------------------| | +----+ +-----+ >From A's perspective ppp0 : local ip:10.1.1.1 peer:10.1.1.254 ppp1 : local ip:10.1.1.2 peer:10.1.1.254 (my ISP givesd me the same peer for concurretn dialupsa) The two tunnels: cipcb0: local:10.2.2.1 peer:10.2.2.2 cipcb1: local:10.2.2.5 peer:10.2.2.6 Both CIPE tunnels work fine. I can ping my other box B fine using either 10.2.2.2 or 10.2.2.6 and the traffic goes across the correct interface. What I want =========== I would like packet by packet load-balancing between A and B. Traffic originating from A going to B will be load balanced packet by packet across cipcb0 and cipcb1. What I have tried ================= ip route add 10.3.3.3/32 equalize nexthop via 10.2.2.2 dev cipcb0 nexthop via 10.2.2.6 dev cipcb1 I also run a tcpdump on each of the two itnerfaces cipcb0 and cipcb1 to see where the traffic goes. On A : ping 10.3.3.3 : this makes all outgoing traffic go through a single link. I tried it while at the same time i ran while true;do ip route flush cache; done but that just made tcpdump show the echo reply packet coming back jump back and forth between cipcb0/cipcb1 with a granularity of changing every 2 seconds or so. weird. All outgoing traffic from A still went through the same cipcb interface. What i have searched for but failed to find =========================== I have found posts that refer to something like ip route add ... mpath rr but can not find which iproute2 package that contains the mpath arguments. Request for help: ================= I currently use 2.6.13 with the config options i listed above. How can I do packet by packet load balancing from packets from A to B? I am willing to change to whatever 2.6 kernel known to work. Where can i find an iproute2 tool that supports mpath argument? i suppose i need this? Anyone willing to help me? best regards ronnie sahlberg, ethereal developer _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
