This chapter covers general networking concepts listed in the
ccie sp lab boot camp blueprint for the written exam. The CCIE blueprint lists some example topics that define general networking, including switching, TCP/IP, routed and routing protocols, PPP, ISDN, and asynchronous communications.
The CCIE Security written exam contains approximately 50 percent security questions and approximately 50 percent general networking questions. This chapter prepares you for the general networking questions. Although the CCIE Security written exam blueprint lists some specific networking topics, it does not, for example, mention Frame Relay, which might appear on the exam. This chapter covers many of the listed and a few of the unlisted general networking topics.
Although these topics are not extensively defined in the blueprint, the
ccie lab boot camp Security written exam might include topics taken from the CCIE Routing and Switching written exam blueprint. This chapter endeavors to cover all bases and provide quality test examples to ensure that you are well prepared to tackle the general networking questions you encounter in the examination.
This chapter covers the following topics:
Networking basicsThe OSI model, concepts, and functions. Topics include the
seven layers of the OSI model and common examples (TCP/IP).
Switching and bridgingThe process todays networks use to switch packets and
traditional bridging methods. Virtual LANs, spanning tree, and Ethernet Channel are discussed.
Routing IPThe most widely used routed protocol in todays Internet, IP, and the routing
CCIE Exams protocols available on Cisco routers, such as RIP, EIGRP, OSPF, and BGP.
IOS commands and configuration examples demonstrate the power of routing IP on
Cisco routers.
PPP, ISDN, Frame Relay, IP Multicast, and AsyncTwo of the most widely used
dialup protocols are PPP and ISDN. Frame Relay is covered briefly to ensure that you have a good understanding of the common terminology used in todays networks. IP multicast and async protocols are also covered.
