QoS policy to:
Classify traffic from Router C into three classes based on DSCP values.
Perform AF for packets with DSCP AF1 1 or AF21, and set the minimum guaranteed bandwidth to 500
kbps for the packets.
Perform EF for packets with DSCP EF, and set the maximum bandwidth to 2000 kbps for the packets.
