Hi, I'm currently trying to set up two link with multipath routing as follow: / ---- Link 0 ----X eth0 Core <-----X Linux box ----> Router \ ---- Link 1 ----X eth1 The goal is to provide big bandwidth at nice price. with a Core router making multipath routing with equal coast. Each ethernet interface on the linux box is a /30 network which is working correctly. But when i try to activate multipath routing with command as follow, always one link is marked as dead. ip route add default nexthop via <gw0> dev eth0 nexthop via <gw1> dev eth1 default nexthop via AAA.AAA.AAA.AAA dev eth0 weight 1 dead nexthop via BBB.BBB.BBB.BBB dev eth1 weight 1 In which case does this problem can occurs ? Don't hesitate for more informations. Kernel : 2.4.12 iproute2 : ss010824 Regards, Pierrick.
