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.

Definitions

Next, booty a few moments to address bottomward the definitions for the afterward terms:

Holddown timer, Invalid timer, Flush timer, Garbage timer, authentication, Update

timer, triggered updates, beam updates, breach horizon, avenue poisoning, poison

reverse, counting to infinity, accost interval, abounding update, fractional update, Avenue Tag

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.
