Very well explained thank you - I enjoyed how clear you were about the connect retry timers and hold timers and when they kick in.

Sir your way of explaining things are way more clearer than the book itself :-). Not sure why you have stopped uploading tutorials. But I am eagerly waiting for more videos to come through.

Thanks for watching and your feedback.. Yes you are absolutely right that I stopped uploading even though I don't know why I stopped. But YES I will start soon......

[@dipanchatterjee]

@@tannetpro Thank you for your response. Would love to learn more about MPLs and rsvp traffic engineering from you. If possible please upload tutorials on those topics. Than you again 🙏

One Clarification : Already TCP hand shake is completed in the initial stages , as mentioned in the video, If TCP handshake ( Session ) fails on the Open Sent it falls back to Idle state !!, can you please explain why TCP handshake will happen again as it is already done ...?

[@tannetpro]

If you are in Open Sent state and that time if any TCP connection get reset like physical connection, interface issue, or reset the BGP then the TCP need to reestablish again as all BGP communication happen top of TCP communication. Here your TCP is the road and your all BGP communication are vehicle now if your road some how break you have to rebuild then only your vehicle can travel right? you can use this analogy for the understanding. And Naveen if you want to drive bit deep on this just follow below RFC doc which is global truth and you can read more on each events. www.ietf.org/rfc/rfc4271.txt

[@TCPeeDump]

Hello, Thank you kindly for the video, one small note - not related to the BGP but how you say "Idle" you pronounce like "IDEAL" and not "idle" is two different words, I understand you're not native speaker, I just try point it out, because that took me some minutes to adjust to :D Btw; your video are very unique in a sense you show config, diagram and explain all same time. Look forward for future videos from you, really appreicated.

[@tannetpro]
