Committed Access Rate Limiting

Scenario:

A host on your network has been surfing the web and transfers files far too much. Your boss is old school and does not like class-based QoS nor MQC. You have to find a way to police traffic from that host before it cripples your network!

Goal:

• Nothing has been preconfigured for you!
• Make the proper physical connections as outlined in the diagram.
• The bandwidth between R1 and R2 is 496 kbps. Configure this.
• Add a static default route onto both R1 and R3 as they represent hosts.
• Ensure you have IP connectivity from R1 to R3 before continuing.
• Without using MQC or CB Policing, police traffic from R1, configured on R2 as follows. Bc should be equal to the CIRs:
• Police all traffic to 496 kbps, dropping all exceeding traffic. Before this traffic is forwarded, apply the additional policing ...
• Police web traffic at 400 kbps, dropping all exceeding traffic.
• Police FTP traffic at 160 kbps, dropping all exceeding traffic.
• Police ICMP traffic at 200 kbps, dropping all exceeding traffic.
