Distance Vector Protocol vs Link State Protocol

Distance Vector Protocols

These protocols are the protocols that are used to determine the best path for the packets on the basis of the distance and these protocols are the protocols that measure the distance by the numbers of the layer 3 device that is router. In distance vector protocols only complete routing table will be transmitted and this process will consume the large bandwidth factor. In most cases if the bandwidth of the link is low than on that link there is a chance to occur congestion.

Link Sate Protocols

These protocols are the protocols that work on the basis of the characteristics of the route like as the bandwidth, cost and also congestion for the determination of the best path and that's all done on the algorithm that is known as the "Dijkstra Algorithm" that is also known as the link state algorithms. In link state protocols only change will be transmitted and this process will save the large using bandwidth factor.

Routing Information Protocol | Distance Vector Protocol

RIP

RIP stands for Routing Information Protocol. It is a distance vector protocol and the maximum capacity of this protocol is 16 routers/15 hop count. RIP is the protocol that administrative distance value is 120 by default it is configurable parameter. And this protocol is based on the Bellman Ford Algorithm. This protocol is a layer 3 protocol but this protocol operate on the application layer that is known as the 7th layer of the OSI model. This protocol is the oldest distance vector routing protocol and this protocol uses port number 520. Split horizon is the built in functionality to avoid the loops in this routing protocol and this technique like that if one router transmit then it will not receive.

Fig:1

There are the three versions of the RIP:

RIPv1

RIPv2

RIPng

RIPv1

Easy to configure.

No complexity.

Broadcast every 30 seconds.

It work only base on hop count.

It is not scalable as hop count is greater than 15.

It only support the classful.

It no support the subnetting.

It use in the small companies.

It is slowest protocol.

RIPv2

Support the subnetting.

Support the authentication.

Support the multicasting at 224.0.0.9 reserved address.

It is standardized protocol.

It VLSM supportive.

RIPng

RIPng is the protocol that is developed for the IPv6 basically it is the supportive version of RIP that for the Internet Protocol Version 6.

Basically it is the same protocol like RIPv1.

Send the updates to it's neighbor every after 30 seconds.

It use the port no 521.

The multicast address for this protocol is FF02::9.

How to configure RIP routing Protocol on two routers

The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination.
