from what I understand, the packets were marked by the firts router as priority 5 critical, and in the second router with output to the ISP, 20% of the bandwidth was reserved for the packets.. so the name of the classmap does not matter, but the marking used in the packets in case (5 critical)
I am a little confused here, why he used 2 routers to create and apply QOS, is it not possible to configure everything on only a single router, i mean from the above diagram can we use only one router directly connected to ISP. And configure everything on it?
