Guh. ifdown doesn't delete the addrs, and once they are, via del_addrs, the link up doesn't result in route creation. 


What distro is this on?

You're not also setting the address via an ip= line on the kernel
command line, or via an initrd?

What's the contents of your ifcfg-eth0 file? (you may have multiple
under different profiles)

(Sorry for the verbosity here)

FC3.
Not setting address via kernel cmd line.
