Youhouuu. TCP is a beast and i'm pretty sure i have only scratched the surface!

I haven’t checked what is exactly asked for the CCNP ROUTE exam however keep in mind that the most important thing (in my opinion) is to have strong knowledge and skills on the mains topics (EIGRP, OSPF, redistribution, PBR, BGP...). Others topics are also important to know as well but they should represent a small part of the exam, they shouldn’t require as much expertise as the big ones.

Everything in the blueprint is equally important. However with TCP i feel i could be studying till infinity so i wanna draw a line.

If you look closely on the blueprint you can see the weightings for each part of the exam.

TCP is in Network Principles which weights only 10%
