Hi,

I have a linux box loaded with RH7.1, 3 ethernet with load balance on 2 ISP.
In theory, if one router stop to work (I have turn off for this try), the Dead Gateway Detection,
would re-instradate alla traffic on other link. This not work...someone have more experience on this?

Have you followed the lartc howto chapter 10?

[LARTC] Dead gateway detection

[Laurens van Alphen]

Hi,

I installed the routing patches at
http://www.linuxvirtualserver.org/~julian/#routes for Linux 2.4.19 and
have a few questions:

Q1: In the Nano-HOWTO on your site, it says to include these statements:
"ip route append prohibit default table <tablename> metric 1 proto
static"
Why? What does it do? If I use these I can't connect to the Internet,
without them I can.

Q2: I have the following multipath route to the Internet:
"default  proto static
        nexthop via GW1 dev eth1 weight 1
        nexthop via GW2 dev eth2 weight 1"
If I unplug eth2 the second route is never marked as 'dead', why?
Only if I 'ifconfig eth2 down' the second route is marked dead. I
thought the patches would detect this?

Thanks,
