• Perform EF for traffic with the DSCP value EF and set the guaranteed bandwidth to 30 Mbps.
Before performing the configuration, make sure that:
• Router C can reach Router D through Router A and Router B.
• The DSCP fields have been set for the traffic before the traffic enters Router A.

Configuration procedure
Configure Router A
# Define three classes to match the IP packets with the DSCP values AF11, AF21 and EF respectively.

# Define a traffic behavior named ef_behav, configure EF in the behavior, and set the guaranteed
bandwidth to 30720 kbps.

# Define a traffic behavior af11_behav, configure AF in the traffic behavior, and set the guaranteed
bandwidth to 5120 kbps. Configure traffic behavior af21_behav in a similar way.
