• A hop count is the number of routers that a packet must pass through to reach its destination.


  • RIP (Routing Information Protocol) is a dynamic routing protocol used in computer networks for routing data packets in IP (Internet Protocol) networks or to facilitate the exchange of routing information among routers. 


  • It is one of the oldest and simplest routing protocols, and it is widely used in small to medium-sized networks.
  • It shares information about network topology with other routers on the network, and each router uses this information to calculate the best path to reach a particular destination.
  • It is a type of Interior Gateway Protocol (IGP) and is used primarily in small to medium-sized networks.

Working Principle

  • RIP operates by using the principle of distance vector algorithm to determine the best path for data to travel between devices on a network.
  • RIP works by having each router broadcast its routing table to its neighboring routers. The neighboring routers receive the updates and use them to update their own routing tables. This process is repeated periodically to ensure that all routers in the network have the most up-to-date routing information.
  • RIP uses a metric called hop count to determine the best path to a destination for data packets to take through the network. RIP assumes that the shortest path is the one with the fewest hops. The path with the fewest hops is considered the best path.

Types of RIP

  • There are two versions of RIP: RIP version 1 (RIPv1) and RIP version 2 (RIPv2). RIPv2 provides some additional features, such as support for Variable Length Subnet Masks (VLSMs) and authentication.


  • Despite its limitations, RIP is still widely used in some small to medium-sized networks and it is supported by many network devices, such as routers and switches.
  • It is simple to configure and manage, and it can be effective in networks with a small number of devices.


  • RIP has some limitations, including a maximum hop count of 15, which can limit its use in larger networks. However, in larger and more complex networks, other routing protocols such as OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol) may be more appropriate.
  • Additionally, RIP does not support multiple paths to the same destination, which can result in suboptimal routing in some situations.
