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.
