Exam N10-008 topic 1 question 251 discussion

BGP (Border Gateway Protocol) is generally used by major ISPs for handling large-scale internet traffic. BGP is a routing protocol that is used to exchange routing and reachability information between networks. It is particularly well-suited for handling internet traffic, as it can scale to handle a large number of routes and is capable of routing traffic across multiple Autonomous Systems (ASes). BGP is the main routing protocol used by major ISPs to exchange routing information with each other and with other networks on the internet. Other routing protocols such as RIP, EIGRP, and OSPF may be used in smaller networks or for specific purposes, but are not typically used by major ISPs for handling large-scale internet traffic.

The Border Gateway Protocol is the internet standard External Gateway Protocol (EGP). BGP detects modifications to routing tables and selectively communicates those changes to other routers over TCP/IP. Reference: https://www.lifewire.com/top-network-routing-protocols-explained-817965

"Open Shortest Path First (OSPF) is one of the Interior Gateway Protocol (IGP), which helps to find the best routing path between the source and the destination router using its own shortest path first (SPF) algorithm. It is a Link-state routing protocol that is used to distribute routing information about data packets within a large Autonomous System."

"Border Gateway Protocol (BGP) is the postal service of the Internet. When someone drops a letter into a mailbox, the Postal Service processes that piece of mail and chooses a fast, efficient route to deliver that letter to its recipient. Similarly, when someone submits data via the Internet, BGP is responsible for looking at all of the available paths that data could travel and picking the best route, which usually means hopping between autonomous systems. BGP is the protocol that makes the Internet work by enabling data routing. When a user in Singapore loads a website with origin servers in Argentina, BGP is the protocol that enables that communication to happen quickly and efficiently."
