Routing Information Protocol – Differences between RIPv1 and RIPv2
RIP stands for “Routing Information Protocol”. Routers use it to interchange details on a network.Its main functions are −
To find out the most effective way to route data on a network
To avoid routing loops
The main advantage of RIP is that its bandwidth utilization is very high and it updates every 30 seconds. However, a maximum of 16 routers can be composed, as it supports only 15 hop counts. Also, its confluence rate is slow.
RIPv1
RIPv1 stands for Routing Information Protocol version 1. It uses Classful routing. The regular routing updates do not carry subnet details and do not support Variable Length subnet masks (VLSM). This is the drawback of RIPv1, due to which it is not possible to have various sized subnets in the same network class.
In addition, all the subnets in the same network must have the same size. Also, there is no reinforcement for router identification, making RIP unprotected from numerous attacks.
RIPv2
RIPv2 stands for hybrid routing protocol version 2. It is a distance-vector routing protocol defined in RFC 1723 and has the characteristics of link-state routing protocols. It is a classless routing protocol which means it involves the subnet mask having the network addresses in the routing updates.
Due to the shortage of RIPv1, RIP version 2 (RIPv2) was introduced in 1993. It was furnished with the ability to help the subnet information and keep up with Classless inter-domain Routing (CIDR).
Difference between RIPv1 and RIPv2
The following table highlights the major differences between RIPv1 and RIPv2.
| RIPv1 | RIPv2 |
|---|---|
| This protocol is a Distance-Vector routing protocol. | This protocol is also a distance-vector routing protocol. |
| It can assist with a complete class network only. | It can assist complete class networks and classless networks. |
| It does not keep up with documentation. | It keeps up with documentation. |
| RIPv1 hop count limit is 15. | RIPv2 hop count limit is also 15. |
| Not good security. | Security is good. |
| For updates, it uses Broadcast traffic. Whether routers are running on RIPv21 or not. They have to process the routing update messages. | For updates, it uses Multicast traffic.
However, multicast traffic weakens the network traffics. Therefore, only routers that are running on RIPv2 will join the multicast group. |
| It does not give the activate updates. | It gives the activate updates. |
| It does not send a subnet mask to the periodic table. | It sends a subnet mask to the periodic table. |
| RIPv1 does not support the VLSM and discontinuous networks. | RIPv2 supports the VLSM and discontinuous networks. |
| It does not support manual route summarization. | It supports manual route summarization. |
