The Routing Information Protocol ( RIP )

Summary of Routing Information Protocol (RIP): I describe Request for Comments (RFC) 1058 (RFC) by describing RIP's basic algorithm / distance vector algorithm, protocol, message format, protocol limitation, , Routing Information Protocol (RIP). . RIP communicates information about the path between the network and the host, so it is very important for network interconnection. It allows hosts and gateways to exchange information for computing routes. Basic Algorithm / Remote Vector Algorithm: RIP is designed for medium scale networks using nearly identical technology.

Routing Information Protocol (RIP) is a dynamic routing protocol for local area networks and wide area networks. Therefore, it is classified as Interior Gateway Protocol (IGP) using distance vector routing algorithm. A device running RIP sends information on all the devices connected to the network every 30 seconds to keep the network reachable and connected. RIP has two versions. Figure 0.23 shows the routing process. Indicates that the port used for routing is UDP 17. There are only two routers connected to each other. You can also see which versions or RIPs are running and whether the distances between the two routers in HOPS COUNT are displayed. The first is one hop from the host and the second one is two hops from the host. Routing information Another thing is that RIP can only support 15 hops per network.

Routing information called RIP protocol version 1 is the initial routing protocol implemented in ARPANET in 1967. The classification in front of RIP is class integrity, distance vector, and Interior Gateway Protocol (IGP). RIP was developed based on the Bellman-Ford algorithm and uses hop count as a metric. Use the minimum number of hops to calculate the best path. Rip limits the number of hosts supported on the network to prevent routing loops and maintain stability. Supports up to 15 hops in the network. The 16th hop is defined as an infinite administrative distance and they become inaccessible and unshareable. Send updates between routers using the broadcast address 255.255.255.255. The RIP administrative distance is 120

Initially, the protocol is divided into routing protocols and routing protocols. The routing protocol is responsible for the actual data transfer. The protocols in this category are TCP / IP, IPX / SPX, and Apple talk. Routing protocols exchange routing information between routers. These include RIP, RIP v.2, IGRP, EIGRP, OSPF BGP, and so on. IGP and EGP are characterized based on autonomous systems. An autonomous system (AS) is a collection of networks within an administrative domain. The IGP protocol is used to exchange router information between the same AS numbers and EGP is used between different AS numbers. Rip, Rip v.2, IGRP, EGRP, OSPF, IS-IS belong to IGP and BGP belongs to EGP
