Seonglae ChoBorder Gateway Protocol
AS announce their routing policy to other AS and routers via the Border Gateway Protocol. BGP is the protocol for routing data packets between AS. Postal service of the Internet who can break internet. Mechanism to exchange routing information between autonomous systems. The reason why multiple path exists for same destination.

bgp is not safe yet until implementing RPKI you
Is BGP safe yet? · Cloudflare
On the Internet, network devices exchange routes via a protocol called BGP (Border Gateway Protocol). Unfortunately, issues with BGP have led to malicious actors being able to hijack and misconfigure devices leading to security problems which have the potential to cause widespread problems. BGP security can be greatly improved by using technologies such as RPKI to sign Internet routes. This page attempts to track the progress of major Internet players (ISPs, transit operators, and content providers) in their progress to adopt RPKI and other technologies.
