Hello, everyone.
I recently switched jobs and was hired to work under an ISP/Telco company. I noticed that I don’t quite understand all the ISP technologies, even those that I’ve studied about.
The thing is, seeing the theory and labbing it is just fine but seeing it implemented in the real world and even mixed with other technologies is where I get a little confused.
For example, I spent a decent amount of time understanding and covering MPLS L3 VPNs. Turns out that they run some sort of L2 VPN and also ATOM or whatever the name is. There is also Metro Ethernet included any many other things that I didn’t fully cover during my studies.
For this reason, I wanted to pursue the CCNP Service Provider certification (SPCOR plus SPRI) to gain a better understanding of all these technologies and learn how and why they are implemented.
What do you think about this? Is this an okay approach? I generally wanted to pursue some other Cisco certs so I don’t mind personally.
What’s troubling me a little is the overall coverage of the material. There are many new technologies that I’ve never heard about - segment routing, traffic engineering (policies, automated, PCE) and so on although the OCG books, NW, and CBT (including cisco documents and a looot of googling) should be able to cover most of these.
If I encounter a question that I won’t understand regarding a technology that Rene didn’t cover, is it okay for me to ask about it here?
That’s all, thank you 
David
