Hi, Dino,

OK, that's what I thought you meant.

Caution: I have managed networks before, but it wasn't recently... people 
with recent experience should probably be saying something :-)

The 10-50 device range is a little higher than what I was used to seeing in 
UNbridged LAN segments. Joe's "200 devices is a moderate size" seemed closer 
to what I expected for a collection of bridged LAN segments.

I look forward to the Problem Statement draft with baited breath, but I 
thought rBridges would be a way of using larger collections of L2 devices, 
since we would be tending to use more paths than just the spanning tree 
path. I think I understand that we're talking about the number of VLANs, not 
the number of L2 devices here, but would expect that there is a fair chance 
we would see larger numbers of VLANs in environments where there are larger 
numbers of L2 devices.

I'll let other people express an opinion now.
