RIP stands for Routing Information Protocol that is an old distance vector routing protocol. It permits the usage of maximum 15 routers for hop count as it is distance vector. RIP has 2 versions. First syncs with full updates every 30 seconds by using doing broadcast. Fews updates and brought about are performed by using 2nd version by the usage of multicast. If we evaluate different routing protocols like OSPF, EIGRP and IS-IS. RIP is quite slow protocol. Because of this, RIP is now not used generally by using networking administrations however its understanding is very important if your beginner in the networking field. In this lesson, we will study basic and advance topics of Routing Information Protocols.

RIP is a distance-vector routing protocol and the easiest routing protocol, to begin with. We’ll begin with the aid of paying interest to the distance vector class. What does the identify distance-vector mean?
Distance: How some distance away, in routing world we use metrics which we simply discussed.Vector: Which direction, in routing world we care about which interface and the IP-address of the subsequent router to trigger it too.
In this picture, we've got three routers and we're jogging a distance vector routing protocol (RIP). As we begin our routers they construct a routing table by default but the only component they know is theirs without delay related interfaces. You can see that this record is in their routing table. In red, you can see which interface and in inexperienced you can see the metric. RIP uses hop rely on as its metric that is nothing greater than counting the number of routers (hops) you need to skip to get in your vacation spot. Now I’m going to allow distance vector routing, what's going to happen is that our routers will reproduction their routing desk to their directly connected neighbour. R1 will copy its routing table to R2. R2 will reproduction its routing table to R3 and the opposite manner round. If a router gets records about a community it doesn’t understand approximately yet, it'll upload this data to its routing table:
Take a note at R1 and you will see that it has realized about the 192.168.2.0 /24 and 3.3.3.0 /24 network from R2. You see that it has brought the interface (Fa1/0) how to attain these networks (that’s the vector part) and you see that it has brought the metric (hop count) for these networks (that’s the distance part). 192.168.2.0 /24 is one hop away, 3.3.3.0 /24 is two hops away. Awesome! You too see that R2 and R3 have mapped their routing tables. Every 30 seconds our routers will ship a full replica of their routing table to their neighbors who can update they're its routing table. So a long way so good, our routers are working and we are aware of the destination to all of our networks…distance vector routing protocols are susceptible to some issues, however, Let me show you what can go wrong:
The Gig1/0 connected on R3 is going down, so it will alternate its routing table. Its status went from zero to Down. Every 30 seconds our routers send a full replica of their routing table to their neighbors and it simply takes place to be that it’s time for R2 to send a copy. R2 sends his full routing table in the direction of R3. What do you suppose will happen?
R3 receives the routing table from R2 and will see that R2 is creating the 3.3.3.0 /24 network with a hop be counted of 1. That’s great is what R3 thinks….a hop count of 1 is higher than having a network that is down. R3 will add these records to its routing table.
