Cisco affirmation competitors are acquainted with BGP at the CCNP level, yet the response to its presentation consistently helps me to remember something I see regularly as the CCNA level. Visit here https://techhandbook.com/
At whatever point I show separation vector conventions in my Ultimate CCNA Boot Camp or Fast Track classes, I ensure my understudies comprehend the numerous guidelines of separation vector steering completely. From that point onward, we proceed onward to OSPF and connection state steering.
What’s more, what do I tell my understudies before we proceed onward to OSPF and connection state? “Take all that incredible stuff you simply found out about separation vector steering and set it aside, since none of it applies here!”
That is about the time I get surprised looks and a couple of things tossed at me. 🙂
What’s this have to do with BGP? All things considered, when you begin examining BGP, you need to put a ton of previously established inclinations aside. It seems like simply one more directing convention, similar to RIP or OSPF, however it’s most certainly not.
So… before we begin considering BGP and taking a gander at a portion of its numerous highlights, we should investigate what BGP is and what it’s most certainly not.
What BGP Does And Who Uses It
In case you’re in a position where you’re accustomed to seeing or working with steering conventions, for example, EIGRP and OSPF, you’re likely currently working with BGP. BGP isn’t a convention you will arrange at the workplace LAN. BGP is utilized to associate self-ruling frameworks, which are exceptionally enormous “assortments” of systems. (Those of you who have considered IGRP and EIGRP know about the ideas of an AS.)
Instead of steering conventions, for example, EIGRP and OSPF, BGP is an outside directing convention. BGP isn’t utilized to locate a particular system rather, it’s utilized to discover the AS where that given system can be found.
A decent method to see it is that systems are contained in Autonomous Systems BGP encourages you discover the AS where a given system is found. Steering conventions, for example, OSPF and EIGRP take it from that point.
