Scenario:

You are the VoIP specialist at the ISP you are working for. To ensure all VoIP traffic has enough bandwidth and low delay you have to implement some Quality of Service settings. It's time to classify and mark some traffic!

Goal:

All IP addresses have been preconfigured for you.
Configure an inbound policy on router Line with the following configuration:
ICMP traffic from router Frank should get a DSCP value of AF33.
RTP traffic from router Frank should get a DSCP value of EF.
HTTP traffic from router Frank should get a IP precedence value of 7 (priority).
All other traffic should get a DSCP value of AF43.

IOS:

The easy way to do the final part of this lab and marking all other traffic would be configure the class-default, which catches everything not matched specified by other class-maps in a policy-map
