WebOpen Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).. OSPF gathers link state information from available routers and constructs a topology map of the network. … Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP is classified as a path-vector routing protocol, and it makes routing decisions based on paths, network policies, or … See more The Border Gateway Protocol was sketched out in 1989 by engineers on the back of "three ketchup-stained napkins", and is still known as the three-napkin protocol. It was first described in 1989 in RFC 1105, and has … See more BGP is "the most scalable of all routing protocols." An autonomous system with internal BGP (iBGP) must have … See more The routing tables managed by a BGP implementation are adjusted continually to reflect actual changes in the network, such as links or routers going down and coming back up. In the … See more BGP neighbors, called peers, are established by manual configuration among routers to create a TCP session on port 179. A BGP speaker sends 19-byte keep-alive messages every 30 seconds (protocol default value, tunable) to maintain the … See more Message header format • Marker: Included for compatibility, must be set to all ones. • Length: Total length of the message in octets, including the header. • Type: Type of BGP message. The following values are defined: See more One of the largest problems faced by BGP, and indeed the Internet infrastructure as a whole, is the growth of the Internet routing … See more Another factor causing this growth of the routing table is the need for load balancing of multi-homed networks. It is not a trivial task to balance the inbound traffic to a multi-homed … See more

WebSep 7, 2024 · BGP is an Exterior Gateway Protocol (EGP) and is typically used to connect autonomous systems (AS) of Internet service providers. BGP calculates routing paths based on several pieces of information, such as AS path, IGP metric, multi-exit discriminator, communities, local preferences, next hop, weight, and origin.
