Charlie,
[First of all, I'd like to ask you to post to
"mailto:rst...@li..."
not to me directly; thanks]

There was a flow in IEEE 802.1w, that was fixed in IEEE 802.1y-d2
(you may  get it from http://www.ieee802.org/1/pages/802.1y.html).
The problem I meet had been discussed in
thread "Question: indirect link fail in 802.1w", you may find this
discussion
in http://www.ieee802.org/1/private/email/msg00370.html and
a conclusion (as far as I remember) in
http://www.ieee802.org/1/private/email/msg00379.html

So, in IEEE 802.1y-d2 you may see:
"17.19.21 updtRolesBridge()
Add bullet item m) to the updtRolesBridge() procedure in 17.19.21 as
follows, immediately
following bullet item l):
m) If the port priority vector was received in a Configuration Message and
is not aged (infoIs =
Received), the root priority vector is not now derived from it, the
designated priority vector is higher
than the port priority vector, selectedRole is set to DesignatedPort and
updtInfo is set."

Best regards, Alex
