Summary

Frame Relay design is an imminent part of enterprise remote access solutions. In fact, the design and provisioned parameters define the ability of the enterprise to use the versatility and flexibility of Frame Relay for its own benefits.

In this chapter, you learned about design parameters, UNI and NNI interfaces, and VoFR and Frame Relay multicast. Extended information about Frame Relay topologies, congestion control, and performance criteria is another major topic of the chapter. The higher-layer protocol encapsulations and fragmentation are provided in detail. In turn, the higher-layer encapsulation requires resolution of Layer 3 and Layer 2 addresses, where ARP, RARP, and InARP are explained.
