From: Chris Meidinger <cmeidinger@sendmail.com> 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...)
This will not work right. One interface can be 10.0.0.1/24, but any added interfaces would need to be /32 (10.0.0.2/32).
I don't know which OS(es) you are using, but that's not true in Linux. I see this all the time at home; if I plug my notebook into the wired LAN and still have the wireless enabled, both will get an IP (in the same subnet) from DHCP. The wired link is the preferred default route by default, but you can easily set up routes for some networks via the wireless link. You can also set up multipath routing to send packets out both links. I think you can also use IP policy routing to control the choice of outbound interface by rule (e.g. based on source address). -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
