two interfaces one subnet

[cmeidinger at sendmail.com (Chris Meidinger)]

Hi,

This is a pretty moronic question, but I've been searching RFC's on- 
and-off for a couple of weeks and can't find an answer. So I'm hoping  
someone here will know it offhand.

I've been looking through RFC's trying to find a clear statement that  
having two interfaces in the same subnet does not work, but can't find  
it that statement anywhere.

The OS in this case is Linux. I know it can be done with clever  
routing and prioritization and such, but this has to do with vanilla  
config, just setting up two interfaces in one network.

I would be grateful for a pointer to such an RFC statement, assuming  
it exists.

Thanks!

Chris
