Relationship between BGP and AS

Hi zaheernew,
AS is an autonomous system.
BGP is a dynamic routing protocol used between autonomous systems (ASs).
BGP is an exterior gateway protocol (EGP). It focuses not on route discovery and calculation, but on selecting optimal routes between ASs and controlling route propagation.
When BGP runs in the same AS, it is called IBGP. When BGP runs between different ASs, it is called EBGP.

I hope it helps!

Nice question brother,
very straight forward answer.

BGP is an EGP used by ASs to exchange routing information with other ASs.

HI friend!
BGP is called Internal BGP (IBGP) when it runs within an AS; it is called External BGP (EBGP) when it runs between ASs

Thanks!
