This book chapter, excerpted from Cisco Press' CCNA INTRO Exam Certification Guide (CCNA Self-Study, 640-821, 640-801), presents the core concepts behind OSI Layer 3. Because CCNA focuses on TCP/IP, the chapter also describes the main Layer 3 protocol used by TCP/IP?namely, the Internet Protocol (IP). This coverage includes IP addressing, IP routing, and some protocols useful to IP's effort to deliver packets end to end through a network.
