Network-Scripts/ifcfg-eth1:1 Problem

[Robert L Cochran <cochranb@xxxxxxxxxxxxx>]

I'm working on replacing my current router machine with a new one. The 
old machine runs Red Hat 9, and has 2 network cards in it: one for the 
internal network and the second for the big wide Internet. The second 
card has two network-scripts associated with it: ifcfg-eth1 and 
ifcfg-eth1:1. The reason is to associate a second IP address with the 
network card.

I've duplicated this on the new machine, which is running Fedora Core 4. 
When I gave it a "trial run" last night, though, eth1 gave a lot of 
"martian source" type errors and appeared to be dead. I've replaced the 
card with a new one. I haven't connected it to the network yet, so I 
don't know if it will really work.

My question is: under Fedora Core 4, is using a configuration script 
called ifcfg-eth1:1 to associate a second ip address with eth1 still valid?

Thanks
