I was initially sceptical when I had to do the same thing as I had bad
experiences with shared addressing over the same interface... but with the
gear over the last five years I've never had a problem with this except with
the specific combination of FreeBSD and Dell boxes.  The problem lied on the
FreeBSD side.

In the Sun world, at least, the host LAN and the IPMI interface have
different MAC addresses even though they share the same physical interface.

Just keep in mind that you need to route multiple networks and the rest
should not present a problem.

I have five racks of Dell gear that I need to figure out how that is going 
to work.  This is my first experience at setting up and using the Dell 
Baseboard Management Controller.  Power should be installed next week, so 
this is going to be a very busy week trying to get ready.

Any suggestions, words of wisdom or web pointers would be appreciated.
