Hey man, thank you so much for your videos, I passed my CCIE SP LAB exam last year, and I used all of your videos to learn. Very useful. Now I have my magic CCIE Number =)
To watch the next video in the course, go here: training.cbt.gg/3ee Scroll down to the skill "BGP Overview." If you're not a current subscriber, you can check it out for free by signing up for a free trial: training.cbt.gg/sbp Hope this helps!
This person has a lot of errors they are not actively working on bgp if they made half of these errors for example at the end of this video and this is the one that got me he refers to EBGP as something in bgp. ebgp is something that has been was the predecessor to bgp protocol no one uses it to the point where it's automatically marked at on most bgp routers as drop all connections if he's to keep he needs to understand that external bgp and is just bgp the e does not exist unless you are referring to a legacy system iggp is part of the bgp protocol and is internal of your own as he described prior to this there were multiple other errors in this thing this is a very poorly worded video this person does not use bgp and apparently they use a different protocol because there is errors and he constantly is referring to how this works versus that instead of how bgp works which predates what he was citing
eBGP and iBGP are both still BGP. An eBGP neighbor is just a BGP neighbor where that neighbor's ASN is different from yours. It is important to distinguish between iBGP and eBGP neighbors because they behave very differently from each other. Some of these important behavior differences are how prefixes are re-advertised differently between iBGP and eBGP, how next hop information is used, multi-hop rules, etc. You say "eBGP is the predecessor to bgp protocol" this statement makes no sense and is false. Every service provider uses an eBGP session to connect to other service providers. You either dont have a solid grasp on BGP or how it is used in today's industry OR are confused on the protocol names/acronyms (eBGP vs EGP) so I dont think it is fair for you to try to discredit the instructor.
