Scenario:
As one of the network engineers for a large frame-relay provider in the US you are asked by your boss to configure QoS. One of your customers insists there will be authentication in the future for his frame-relay connection. You don’t have to configure authentication right now but you remember you can do this by using PPP on a frame-relay link. You do have to setup QoS right now though…
Goal:
- All IP addresses have been preconfigured for you.
- Configure Multilink PPP on the frame-relay link between router Kos and Quall.
- Classify and mark TELNET and HTTP traffic on router Kos and Quall. Use DSCP value AF21 for TELNET traffic and AF31 for HTTP traffic.
- Create a policy on router Kos and Quall with the following configuration:
- TELNET traffic should have 64Kbps of priority bandwidth.
- HTTP traffic should have 10% of the remaining bandwidth.
- Enable Link fragmentation and interleaving and ensure there is a delay of 20ms on the frame-relay link.

Using CBWFQ you can classify the traffic and police it as needed. To configure LFI on the Multilink interface this link should help
