Description of different routing protocols
RIP V2 –
It stands for routing information protocol version 2 and is widely used for the
configuration of the routers because it can be used easily. The version 2 is an improvement
for the older version and used for the configuration of the smaller network. The RIP follows
the distance vector routing and it has the limitation that is it cannot support for the hops for
more than 15 hops. If there are more than 5 hops it becomes infinite for the router configured
with RIP and the route becomes invalid. There are several security mechanism used by RIP
for the prevention of the incorrect data packet or message to be transmitted to the different
address.
The RIP may not be a choice for the network administrator to application in the
current filed for the configuration of the flow of data packets in the network. It uses the user
datagram protocol that is connection less and thus it is not reliable. There are some deficiency
in the version 1 of RIP and thus the version 2 was introduced in the year 1993 (Masruroh,
Fiade & Iman, 2017). The RIPv2 was designed for carrying the subnet information and inter
domain routing for maintaining backward compatibility. The routing table of the router is
multicast to the adjacent routers in case of the RIPv2 but the version 1 broadcasts the routing
table. Tags are added to the version 2 for allowing the router to distinguish between the
different routes that are identified using the RIP protocol.
OSPF –
The open shortest path is used as a routing protocol for the configuration of the router
and it follows the link state routing for the transmission of the data packets in the network.
The link state routing protocol is developed for the interior gateway protocol and supports the
CIDR model. Unlike the RIP the OSPF supports large enterprise network and thus used by

the large service providers for the management of the shortest path and increase the
efficiency of the transmission of the data packets. In case of the RIP the shortest path is
calculated based on the number of hops that are needed to be passed for reaching the
destination address if there is a change in the network it cannot adapt the change but the
OSPF routing protocol is developed such that the cost of the route is identified after analysis
of the bandwidth, load and delay for sending and receiving the data packets.
The cost of the link can be administered and monitored and for its adoption for the
large enterprise network (Lindem et al., 2016). A link state database is maintained for the
management of the topology and its implementation in the current network. The cost of each
of the router should be calculated and stored in the database by sending a hello message after
a regular interval of time for identification of the cost of the neighbour link and updating the
database for recording all the neighbourhood routing information. The link state information
is flooded for management of the synchronization and it is used for continuously updating the
database of the link state. The OSPF routing protocol is used for dividing the network into
different routing areas and simplification of the administration of the network and optimizing
the utilization of the resources and optimizing the data traffic. The area that is added to the
router should be connected with the main backbone area and configured for the maintenance
of the interconnecting routing. The link failures and converges are easily identified by the
OSPF and new route is selected for the management of the relationship with the other routers
connected in the network.
EIGRP –
It stands for Enhanced interior Gateway Routing protocol and operated on the
principle of advanced distance vector routing protocol. It helps in taking automatic decision
for configuration and routing the data packets. The EIGRP protocol is developed by Cisco
