BGP route selection process

BGP (Border Gateway Protocol) route selection determines the best path for data to travel across the internet. When multiple routes exist to reach a destination, BGP evaluates them based on factors like route preference, length (fewer hops), and policy rules set by network administrators. It prefers routes with higher priority settings, shorter paths, and more specific addresses. The goal is to choose the most efficient, reliable, and policy-compliant route, ensuring data reaches its destination quickly and securely. This process helps maintain a stable and optimized internet routing system.
