Thanks Brooks for the feedback.

I was just about to do a reboot with my config before I caught your 
message. I'll update the config and run with it.

While perusing the 'net in order to try to find a solution prior to 
posting, I came across a couple of other posts (I can't remember if it 
was specific to this list) in which the recommendation appeared to be 
incorrect for this exact setup I desired (ie: the recommendation failed 
miserably).

I'll post back with the results in case anyone else here has been 
interested in 'Cisco style' (as I for some reason refer to them as) 
sub-ints on FreeBSD.

Steve
