The Border Gateway Protocol (BGP) allows internal and external networks or autonomous systems (AS’s) to exchange routes. BGP is a path-vector routing protocol, which simply means that its job is to exchange routing information between autonomous systems to find the most efficient path for your data to the Internet. Each BGP router connects to its

When a router learns multiple routes to a specific network via multiple routing processes (or routing protocols, such as RIP, RIPv2, IGRP, EIGRP, and OSPF), it installs the route with the lowest administrative distance in the routing table. Load balancing is a standard functionality of the router software, and is available across all router platforms.
