Most are /22 but varies from /29 to /20. We do *no* cross-backbone 
trunking of VLANs.

Huh? Large Ethernet broadcast domains are just stupid. :-)

Seriously, if we could pull it off, we would have one end station per 
broadcast domain (yes we could make that work). So I'll say "management" 
reasons, but really it is vendor limitation, not because they can't 
handle bigger but because they haven't been listening to our ideas of 
how to make it smaller.
