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.
What problems can you solve by configuring summarization?
By configuring summarization scalability is achieved. EIGRP limits advertisements, minimizes the size and optimizes the speed of the routing table, limits route recalculation, and holds down the amount of memory and CPU resources used.
By summarizing query scoping is also solved where queries do not stop until they reach a dead end. Summarizing creates this dead end and prevents SIA situations and speeds convergence.

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.
