Golden advise - The spreadsheet thing! Really loved it. Can you talk more about the time estimation you give yourself planning wise for every topic? Like do you set a time frame to study a certain technology on the spreadsheet or not? And if so, how do you estimate planning wise?

I would be interested in this, Rob.

- I read on Wikipedia article titled; Internet Backbone = It talked about how a country was having a revolution, so the government wanted to disconnect communication between the protestors, and cut the internet, the article says; - The ISP infrastructures there were not affected but Instead, “the government shut down the Border Gateway Protocol (BGP) sessions announcing local routes. BGP is responsible for routing traffic between ISPs.” -- Can you talk about how they’d do that configuration wise? Cause this sounds very interesting!

- Also how much of a topic is enough? When you lab the topics required in the Cisco Curriculum and study everything on the Cert Guide book? Now is it enough? or what?

- So if I understand this correctly (please excuse me if I don’t): The reason IS-IS AND iBGP are used in the provider core is; iBGP is used to avoid redistribution the eBGP PEs, correct? Cause if it was just IS-IS, the PEs would have to distribute all that in the ISP core which would result in huge CPU utilisation and resources usage, correct? Because why else would we utilise 2 IGPs in 1 AS (ISP core).

- So from what I understand from you; the Cisco documents and RFC are not compulsory to study. Correct?

= Scenario question; - If we have CE1 connected to the LAN, CE2, PE1 - CE2 connected to the LAN, CE1, PE2 - Each CE1 is connected ONLY to 1 PE (meaning CE1 is not connected to PE2 and CE2 is not connected to PE1). - The PEs are connected via the ISP core (obviously). - Now, if I want to have a redudency scenario, that traffic goes and is received from CE1 only, and only if CE1 falls, or PE1 falls, does traffic go to CE2. How can we do this BGP wise? For incoming and outgoing traffic == This question confused me. I was asked this in an interview. Part B of the question; - If we apply an HSRP on the CEs for the LAN traffic as the gateway, and the primary router falls, how would traffic shift to the backup router? What is the mechanism that would cause the traffic to shift? ==== I’m not sure what the answer they want is? Did they want me to say to set up 2 static routes and one backup for example??

I’d be very interested in an enarsi workbook that I could follow along on what to configure so I could set up my own Eve topology

- Is there a practical workbook that recommend for the CCNP ENARSI?
@alik59424 ай бұрын
It's good idea about workbook and eve topology for enarsi, but can you please use either IOSv-L3 (not CSR1000v) or IOL-XE L3 images for the topology? New CML 2.7 has L2 and L3 IOL-XE images. They're quite new and don't need powerful CPU. But please, don't forget about "real life" networking course 😄

- Can you give us an example on eBGP route-reflector routers?

- How do you deal with forgetting details of a topic? Its very frustrating. Its like you have to revise everything you know almost daily or you forcefully forget them.

- I never thought of that till you mentioned it. The ISPs or internet rather; is made up of many ISP rings with no core!!! Can you explain that or talk about that in some details please. - In that sense, there is no such a thing as “The Internet Backbone” or “Internet Core” correct?? - Just a thing to consider; consider making an AMA episode or partial episode about that and relate that to the labs your working on or so.
