In this video, David Smith covers what BGP is, why BGP is used, and what makes BGP different from a protocol like IGP. If you are learning networking for work or to earn certifications, you need to understand how BGP works.
BGP stands for border gateway protocol. BGP is responsible for passing routing data between those autonomous systems. Have you ever wondered how data know how to get from one building in your company to another satellite office? BGP can play a big hand in that if your organization uses autonomous networks.
Service providers and large businesses alike love BGP. It’s an extremely scalable protocol, and it is easily scalable. That doesn’t mean that the scalability of BGP comes with detriments, though. Performance can suffer due to its scalability.
Like all things in IT, BGP has trust issues, too. It makes sense. BGP is designed to help route traffic between different domains. So, at its core, BGP is non-trusting.
Those are only a few of the interesting tidbits that you need to know about BGP. This video contains more information, and even still, it barely scratches the surface. So, are you ready to start learning about BGP? Then let’s get into it!

Finally some SPCOR content from CBTN
You are one of the best cbt trainers. Amazing SPCOR course 👏👏👏
A perfect summary. Thank you.
A great cover of the basics, thanks.
Very informative. Thanks. 😅
great short presentation, it would nice if you add another bullet point for network security benefits on using this protocol compare to others.
Thank you
thank you
Finally!

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.
