Thanks, Tim. I have went through the Doyle book in the past....it good
to hear there is a new edition (I'll pick that up). You can never get
too far away from the basics. I understand the concepts on the
summarization...I'm just looking for places where there are practice
examples to help with the speed. (I have done my own, but it not that
fun when you already know the answers). ;-)

Dave,
If you don't have it, you MUST get the Routing TCP/IP vol 1 book by Jeff
Doyle. BTW, Cisco Press just released a 2nd edition of this classic.
Jeff
has a whole chapter on Summarization and there are practice questions at
the
end of the chapter.
I would say there are 4 aspects to mastering this skill:
1. Understanding the concept (fairly easy but also easy to get
confused)
2. Practicing converting from dec to binary and back.
3. Knowing which command to use in which situation (the different
IGP's
use different commands).
4. Recognizing the requirement in the lab - The lab might not use
the
word "Summarize" in the task you're asked to complete but would instead
require you to allow only one prefix in the route tables of various
routers
or ask you to configure your network such that the route table on router
X
looks a certain way.
HTH, Tim

Does (or has) anyone found any good practice materials for working with
address summarizations? I am looking for some materials to help speed
up on
summarizing addresses. Or, any good techniques? For example, where you
may
have a group of addresses and summarizing them in two ACLs.
TIA, Dave
