Scenario 10-4 Answers

This scenario actually ends up as a fairly straight-forward configuration. With VC-based
technologies, link compression cannot be implemented because the Layer 2 headers are
compressed. Frame Relay implementations have specific compression commands that
enable payload compression. Therefore, that is the task for this entire scenario.
Example 10-18 shows the configuration of compression on the Fort Worth router. Note
that the compression is configured on the major interface, not the subinterface. Frame
Relay traffic shaping is not enabled by default. It is simply mentioned as a reminder that
you cannot compress and traffic shape at the same time.

As mentioned, compression options are limited with VC-based deployments. Example
10-19 shows the configuration of compression on the Atlanta router.

Finally, the San Mateo router must be configured. By now, you should have the idea.
Example 10-20 shows the configuration on the San Mateo router.
Example 10-18
Compression Configuration on the Fort Worth Router
interface serial 0
encapsulation frame-relay
no frame-relay traffic-shaping
frame-relay payload-compress
Example 10-19
Compression Configuration on the Atlanta Router
interface serial 0
encapsulation frame-relay
no frame-relay traffic-shaping
frame-relay payload-compress
Example 10-20
Compression Configuration on the San Mateo Router
interface serial 0
encapsulation frame-relay
no frame-relay traffic-shaping
frame-relay payload-compress
