Basic features of BGP Protocol

Question

What are the basic features of BGP Protocol? How it is distinct to other protocol.

Answer 1

Border Gateway Protocol is the core routing protocol. It works by sustaining a table of IP networks that designate network reach capability among autonomous systems (abbreviated as AS). It is explained as a path vector protocol BGP doesn’t use traditional IGP metrics, although makes routing decisions totally based on path, network policies, and/or rule sets. The BGP substitute the EGP routing protocol to permit completely decentralized routing in order to permit the elimination of the NSFNet internet backbone network.
