Explanation

RIP and BGP are two popular examples of distance vector routing protocols. Important Points Routing Information Protocol (RIP) It is one of the oldest distance-vector routing protocols which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. The largest number of hops allowed for RIP is 15, which limits the size of networks that RIP can support. Border Gateway Protocol (BGP) It 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 rule-sets configured by a network administrator. Additional Information OSPF (Open Shortest Path First) This protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network. SPF It establishes a method for receiving mail servers to verify that incoming email from a domain was sent from a host authorized by that domain’s administrators. It piggybacks on the well-established Domain Name System (DNS).
