Leave the multi homing to >the routers(or my preference layer 3 switches). It's worth noting that some software allows one to specify the outgoing IP (e.g. using inet_interfaces in postfix or sourceaddress with innd). This can be very useful if one has a role IP, say news.example.com, and wants to be sure that outgoing connections originate with a specific IP address so your news partners don't have to mess with their incoming configuration files. I did see some ``interesting'' issues on an private LAN where a server had multiple IP addresses on the private interface. NFS mounts were failing to the primary IP, and after doing some tcp sniffing, I found that the return UDP packets were originating from one of the aliased IP addresses (this was SuSE 9.0 Pro). I fixed the problem by forcing NFS to use tcp conneections rather than beat my head against the wall trying to figure out why this was happening.
