Local-Area Networks and LAN Switching - CCIE Routing and Switching Exam Certification Guide - page 188

This chapter covers the following topics needed to master the CCIE Routing and Switching
(R&S) written exam:
•

Physical Layer Access —CCIE blueprint requirements of physical access, such as
T1, encoding, digital signal level 3 (DS-3), Synchronous Optical Network (SONET),
and Synchronous Digital Hierarchy (SDH)

•

X.25 —CCIE blueprint requirements on X.25 topics, such as addressing, Link Access
Procedure, Balanced (LAPB), error recovery, permanent virtual circuits (PVCs), and
protocol translation

•

Frame Relay —CCIE blueprint requirements on Frame Relay, such as Local
Management Interface (LMI), data-link connection identifier (DLCI), PVCs, traffic
shaping, committed information rate (CIR), forward explicit congestion notification
(FECN), backward explicit congestion notification (BECN), and discard eligible
(DE) bit

•

Integrated Services Digital Network (ISDN) —CCIE blueprint requirements on
ISDN, such as Link Access Procedure on the D channel (LAPD), Basic Rate Interface
(BRI), Primary Rate Interface (PRI), mapping, B and D channel, and Dial backup
using ISDN, as well as high-level data link control (HDLC) and Point-to-Point
Protocol (PPP)

•

ATM Architecture —CCIE blueprint requirements on Asynchronous Transfer Mode
(ATM), such as PVC/switched virtual circuits (SVCs), ATM adaptation layer (AAL),
Service Specific Connection Oriented Protocol (SSCOP), User-Network Interface/
Network-to-Network Interface (UNI/NNI), cell format, Quality of Service (QoS),
Request For Comments (RFC) 2684 and 2225, Private Network-Network Interface
(PNNI), and Interim-Interswitch Signaling Protocol (IISP)
