How do you do for study a big amount of information?

[ccnaluna93]

I mean, for CCNP, we have 3 books, For the Routing Book we have like 1000 pages, how can you memorize everything in order to pass the exam and keep the knowledge.

What technical do you use?

[balaji.bandi]

It all depends how deep dive you want go in. Like Phd in RNS.

or do basic concepts and understand the login, when you get in to hands on job, you learn better understand.

end of it how deep you want to go. some times apart from this you need to RFC also for the frame work.

So eventually you learn most of it by experience.

Hello ccnaluna,

first of all you need to understand the basic principles of routing.

So understanding the key concepts is very important.

There are some details that may need to be memorized (for example that OSPF uses IP protocol type 89 and so on).

You can also use some labs to test some features for examples using GNS3 emulation.

This was something not available many years ago.

The move from CCNA level to CCNP level requires also some job experience.

If you already work in the networking going for CCNP is easier and more useful.

Just to name few very key items you need to understand:

classless routing / classful routing  (there are three different contexts for this)

What means subnetting.

What is VLSM and how routing protocols can support it.

What is route summarization and why it is useful.

The most spefic route is used.

Then comes the specifics of RIPv2, EIGRP. OSPF (IS-IS).

IT is a long journey to improve ourselves, but if you are interested in details like for example why an eBGP session fails to form between not directly connected neighbors.

Curiosity is the key.

The forums can also provide a lot of information about specific doubts/issues. Also the Cisco Learning Network.

Hope to help
