There are several interior gateway protocols, but only one current exterior gateway protocol. What is this protocol, and what characteristics does it have?

What will be an ideal response?


ANSWER: The Border Gateway Protocol (BGP) is the only current exterior gateway protocol, and has been dubbed the "protocol of the Internet." Whereas OSPF and IS-IS scouting parties only scout out their home territory, a BGP scouting party can go cross-country. BGP spans multiple autonomous systems and is used by edge and exterior routers on the Internet. Here are some special characteristics of BGP:
* path-vector routing protocol-Communicates via BGP-specific messages that travel between routers over TCP sessions.
* efficient-Determines best paths based on many different factors.
* customizable-Can be configured to follow policies that might, for example, avoid a certain router, or instruct a group of routers to prefer one particular route over other available routes.
