I'm not sure I fully understand the question.
Are you saying that you are losing your ethernet interface(s) and when you
bring them back up, your routing tables are not the same as when you boot?
If so, there are probably a number of ways to fix this.
1. put routes into /etc/sysconfig/static-routes. At least linuxconf can
help you set this up, but don't know the format off the top of my head.
2. Create a file /etc/sysconfig/network-scripts/ifup-local that looks
something like this
#!/bin/sh
#
# local ifup handling. DEVICE passed in
DEVICE=$1
case $DEVICE in
eth0)
# put your route statements here
;;
eth1)
# put your route statements here
;;
esac
As far as preventing this from happening, I have no idea.
I'd actually like to know if there are any built in mechanisms to keep a
dhcp based interface up, or check on it and ifdown/ifup it as needed. Just
today I had to talk my Mom through doing an ifup/ifdown on here DSL
interface after they had a bad storm last night. I'm not sure how it
happened, but they lost their DSL connection and at least today their DSL
modem looked fine. If no-one has a better plan, I'm going to write a
script to monitor the connection. Losing your connection to the box is the
only downfall to trying to maintain a Linux box for your (don't tell her I
said this) near computer illiterate mother who like 1K miles away :)
