For example, eth0 is 10.0.0.1/24 and eth1 is 10.0.0.2/24, nothing like bonding going on. The customers usually have the idea of running one interface for administration and another for production (which is a _good_ idea) but they want to do it in the same subnet (not such a good idea...)
I just posted on this, but I didn't really address your original question, so: I'm not aware of anything in the RFCs or other standards which prohibits this. But then, I haven't gone looking, because... It *can* be made to work in practice, for certain scenarios. For example, if you're talking a web server, and you bind the "production" site to 10.0.0.2 and the "administration" site to 10.0.0.1, and configure policy routing (you said Linux, right?) to route appropriately, it should work. It works because Apache can bind sites to individual interfaces. -- Ben
