I don't think the provider has got a bad configuration, partly
because we have spoken with them about this several times and
partly because of what I didn't include below, that we have the
same problem for every vlan they gave us (30 in all, 6 each to
5 locations). As long as we only use one vlan to each location,
everything works. When we add another vlan to one of the locations,
all 6 vlans to that location goes into blocking mode because of the
errors below. It could possibly be a systematic error somewhere.

Great thread on the subject. I hadn't seen that, I will read it and
check for ideas.

Many thanks!
