interdomainreititystä
Interdomain reititystä, commonly known as interdomain routing, is a fundamental concept in computer networking that deals with how data packets are forwarded across different autonomous systems (ASes). An autonomous system is a collection of IP networks and routers operated by one entity that has a single, clearly defined routing policy. Interdomain routing is distinct from intradomain routing, which manages routing within a single autonomous system.
The primary protocol used for interdomain routing is the Border Gateway Protocol (BGP). BGP is a path-vector
BGP allows ASes to exchange routing information and make decisions based on complex policies. These policies
