RIP uses hop count as its metric, where each hop represents a router. The maximum hop count allowed is 15, which means any destination that requires more than 15 hops is considered unreachable.
The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols used in computer networks. It helps routers determine the best path for data to travel across networks by calculating the shortest distance (in hops) to reach the destination. RIP uses hop count as its metric, where each hop recodesents a router. The maximum hop count allowed is 15, which means any destination that requires more than 15 hops is considered unreachable.
RIP is used in small to medium-sized networks where simplicity and ease of configuration are important. It automatically adjusts to network changes, such as router failures, by periodically updating its routing table. It's an easy-to-implement solution, especially for networks that don’t require the scalability and complexity of more advanced protocols like OSPF or EIGRP.
In this section, we'll walk through setting up RIP for two routers, each connected to a different network. We’ll configure RIP on both routers to ensure they can exchange routing information and properly route traffic between the two networks.
Below is a diagram of the network topology we will be using for the RIP setup:
"Hi, and welcome to this video where we’ll be talking about the Routing Information Protocol, or RIP. RIP is a routing protocol that helps routers in a network find the shortest path to route data by calculating hop counts. In this video, we’ll set up RIP between two routers to demonstrate how it works. Let’s get started!"
"RIP is a distance-vector routing protocol. It uses hop count as its metric to determine the shortest path to a destination. A hop is defined as passing through a router, and the maximum allowed is 15 hops. If a destination requires more than 15 hops, RIP considers it unreachable. This makes RIP simple but less efficient in large networks."
"RIP is ideal for small to medium-sized networks. It’s easy to configure, automatically adjusts to network changes, and doesn't require complex configurations. However, it may not be suitable for large-scale networks due to its limitations in scalability and slower convergence times."
"Let’s move to the setup. We have two routers: Router 1 and Router 2. Each router is connected to a different network. Our goal is to configure RIP so that both routers can exchange routing information and route traffic between the two networks."
"On Router 1, enter configuration mode and enable RIP by typing the following commands:"
Router1# configure terminal Router1(config)# router rip Router1(config-router)# network 192.168.1.0 Router1(config-router)# network 192.168.2.0 Router1(config-router)# exit
"Here, we’ve enabled RIP and specified the two networks Router 1 is connected to: 192.168.1.0 and 192.168.2.0."
"Now, let’s configure Router 2. On Router 2, we will follow similar steps, but we will specify the networks it is connected to:"
Router2# configure terminal Router2(config)# router rip Router2(config-router)# network 192.168.2.0 Router2(config-router)# network 192.168.3.0 Router2(config-router)# exit
"In this case, Router 2 is connected to networks 192.168.2.0 and 192.168.3.0."
"To verify that RIP is working correctly, we can check the routing tables on both routers."
"On Router 1, we type the following command to view the routing table:"
Router1# show ip route
"And on Router 2, we do the same:"
Router2# show ip route
"You should see the routes to the other network listed in the routing table, which means RIP is successfully exchanging routing information between the routers."
"And that’s it! We’ve successfully configured RIP on two routers, allowing them to exchange routing information and route traffic between two networks. RIP is a great choice for smaller networks, and now you have a basic understanding of how to set it up. Thanks for watching!"
