I finally discovered that this isn't a problem with the kernel, but rather
with the way I set up my /etc/sysconfig/network-scripts on Red Hat 2.1
to make aliases work. The problem was that for every alias, a network route
and a default route were being added, and they were replacing the previous
ones. I've since changed my ifup-eth script to only add a host route if
NETWORK is not defined (in the ifcfg-eth? script).
In Red Hat 4.0 IP aliases are officially supported, so presumably you won't
have to worry about this. I haven't tried it yet though.
Cheers,
Eric
