BGP Analogy
- BGP, or Border Gateway Protocol, enables communication between different autonomous systems on the internet.
- It's analogous to a mail service, routing data packets like letters through various postal offices (autonomous systems).
Autonomous Systems
- An autonomous system (AS) represents networks under single administrative control, often mapping to an organization.
- Multiple ASes interact via external BGP (EBGP), while internal BGP (IBGP) manages routes within an AS.
When to Use BGP
- Organizations with a single internet connection can typically use static routes.
- Consider BGP when needing redundancy or optimizing costs among multiple ISPs.
