Memory Builders
The CCIE Acquisition and Switching accounting exam, like all Cisco CCIE accounting exams, covers a fairly
broad set of topics. This area provides some basal accoutrement to advice you exercise your anamnesis about
some of the broader capacity covered in this chapter.
Fill in Key Tables from Memory
Appendix E, “Key Tables for CCIE Study,” on the CD in the aback of this book contains abandoned sets
of some of the key arbitrary tables in anniversary chapter. Print Appendix E, accredit to this chapter’s tables
in it, and ample in the tables from memory. Accredit to Appendix F, “Solutions for Key Tables for CCIE
Study,” on the CD to analysis your answers.

Further Reading
This affiliate focuses on TCP/IP protocols; abundant added advice can be begin in the RFCs
mentioned throughout the chapter.
The RIP RFCs listed in Table 7-5 accommodate acceptable references for RIP concepts.
Jeff Doyle’s Acquisition TCP/IP, Volume I, Second Edition, (Cisco Press), has several excellent
configuration examples and provides a complete account of RIPv2 concepts.
