ACKNOWLEDGEMENTWe can write a 1000 page book, but we can’t find enough words to describe thecredit Mr. Siddiq Ahmed deserves for what is good about this book. Your ability to guideus made the toughest things easy in developing this book. We still refuse to write a bookunless you develop it!!Behind the scenes at Netmetrics is a vast array of talented people – all of whommade it possible to develop the book. People, who provided the right equipment in theright time, people who maintained a friendly atmosphere to finish the work in time. Manythanks to you all for the hard and good work.Thanks to Nizam, Anwar, Afsar, Awadh, Sreenivas and Mr. Prasad for findingbetter ways to describe how the technical pieces fit together, for fixing errors.Thanks to Mr. Abdur Rahman for giving us the time we needed to work on thisbook and by making sure the job was fun.Finally, no acknowledgement section could be complete without acknowledgingourselves, who took all the responsibility and dedication in completing the book.Finally, to GOD, who gives us strength when things are tough, and peace beyondbelief – THANK YOU!!!Page 2 of ll contents are copyright @ 2007-2010All rights reserved.

Task 1Configure EIGRP according to the above scenario. Configure R1 ( S0, E0 ), R2 ( S1, S0,E0 ) in EIGRP AS 100 and R3 ( S0/2 ) in EIGRP AS 200. Do not advertise network30.0.0.0 in EIGRP process. R1 wants to send packets to network 30.0.0.0. Use the Ipdefault-network command to accomplish this task.
