hi,
i would like to share this
/etc/sysconfig/network-script/route-eth0
GATEWAY0=XXXXXX
NETMASK0=XXXXXX
ADDRESS0=XXXXXXX
a delete route command with "route del -net xxxx...." will work but if the above exist and you reboot the linux then old route will be invoke on that config-route.
you need to modify it so that succeeding reboot will change it.
regards
