Frame Relay If I were to rank all of the topics addressed on the CCIE written and lab exams in order of importance, frame-relay would probably be number one on my list. I cannot emphasize enough that in order to obtain CCIE certification you must know frame-relay cold. Frame-relay provides a foundation for your understanding of other technologies such as ISDN, ATM, X.25, and SMDS. If you understand the Nonbroadcast Multi-Access (NBMA) nature of frame-relay, then learning the other technologies will be much easier since all of the NBMA technologies have similar configuration problems.
