Hi ! I have a problem with equal cost multipath. I have two 2 mb lines to the internet with diffrent routes. I just use one line on our firewall, but are going to set up the other line now. But when i set it up like this route add -net 0.0.0.0 gw xxx.xxx.xxx.xxx netmask 0.0.0.0 route add -net 0.0.0.0 gw xxx.xxx.xxx.xxx netmask 0.0.0.0 and i have the net set up like this internet router router switch fw the traffic stops if one of the routers goes down, it does not fall back to the other router (like i want it to do). Then i thought that if I set up one interface to each router and then run a ping script that looks if the router in down or not. And if it is down it takes away the route to that router untill it is alive again. Something like this. ( I can´t make scripts in linux so I don´t know if anything is right in the script). But it might show what i want the script to do :) #!/bin/bash :start ping -c 1 -I eth0 www.download.com &> ping1 ping -c 1 -I eth1 www.download.com &> ping2 cat ping1 | grep icmp_seq=0 &> $A1 cat ping2 | grep icmp_seq=0 &> $B1 # eth0 ping seq if [ "$A1" = " " ] do echo down &> $ETH0 done if [ "$A1" = !"
