Working from the my last couple of EIGRP posts I am going to try and crystallize some of the material found by working through questions found in Stewart, B,D., Gough, C (2008). CCNP BSCI Official Exam Certification Guide, Fourth Edition. Indianapolis: Cisco Press.
Give two reasons why you might want to change the hello timer?
One might want to change the hello timer would be to decrease the period between hellos (thus increasing the amount of hellos sent). This uses more bandwidth marginally but increases stability and causes faster convergences. This is a useful practice in WANs like non-broadcast multiple-access (NBMA) technologies where EIGRP assumes low bandwidth and sets hello timers to 60 seconds.

Notes and Notices:
This is a part of my personal BSCI notes and research to assist myself in learning and understanding the concepts and theory for the BSCI exam. I learn by making notes reading and writing things down and wish to file them where I can’t lose them. These notes are not to be seen, judged or mistaken for replacements to Cisco recognized and authorized training which I personally support and attend and suggest you undertake if you are going for the BSCI Certification.
