Hi Petr.
Bridging dot1q tagged frames and modifying them along the way are two
different stories. I don't have this experience so I cannot say for sure
if it works or not. Might be interesting to try in lab environment.
For Bill it most likely was a misleading from ISP staff when they asked
him to mark video traffic with cos = 1.
I would avoid L2 QoS implementation across CE-PE border (unless ISP
means this indeed), L3 QoS making is much more reliable and scalable all
in all.
