In the modern world, the computer network is based on a technology whereby routing
protocols are used to transfer data across the Internet Routing protocol. A multiprotocol network
is designed in a discontinuous manner thus there is the implementation of classless protocol
RIPv2 on all the routers (Davis, 2014). Routing makes it possible to build the relevant routing
tables, learn of all routes on the network and make the necessary routing decisions. A Routing
protocol specifies how the routers in the network communicate hence useful in the selection of
routes between the nodes found in the network. The routing protocols in this proposal are RIPv2,
OSPF, and EIGRP. It is essential to understand that today’s networks do not support a classful
IP addressing when creating a multiprotocol network. Therefore, the network design of the
multiprotocol network uses classless RIP in all the routers.
Creating a multiprotocol operational network using EIGRP, OSPF, and RIPv2 protocol
Enhanced IGRP refers to an advanced distance vector that has some link-state protocols
properties. It addresses some limitations that are present in the protocols of conventional distance
vector routing such as high bandwidth consumption and slow convergence in a network
considered being in a steady state (El Idrissi et al…, 2017). OSPF was developed for use in
Internetworks that are based on Internet Protocol (IP) and is referred to as the IGP (Interior
Gateway Protocol). The distribution of routing information by OSPF takes place in routers found
in the autonomous system. RIPv2 is considered a distance-based routing protocol that uses the
metrics of router hop counts (Olifer & Olifer, 2005). The maximum hop count values that RIPv2
support is 15 and any router that exceeds 15 hops away are considered an unreachable network.
RIPv2 can support the Classless Inter-Domain Routing (CIDR) and subnet information.



Moreover, RIPv2 is usually referred to as a classless protocol thus it can include the subnet
addresses in the updates found in the routing.
OSPF is an Interior Gateway Protocol (IGP) developed for use in Internet Protocol (IP)-based
internetworks. As an IGP, OSPF distributes routing information between routers belonging to a
single autonomous system (AS).
RIPv2 is Distance Vector Routing Protocols that use router hop counts as their metrics. It
supports a maximum hop count value of 15. Any router farther than 15 hops away is considered
to be unreachable.
Configuring RIPv2 (RIP NETWORK)
RouterA(config)#router rip
RouterA(config-router)#version 2
RouterA(config-router)#no auto-summary
RouterB(config)#router rip
RouterB(config-router)#version 2
RouterA(config-router)#no auto-summary


Configuring OSPF (area 0, area 1, and area 2)

Configuration EIGRP
R1(config)# int Serial0/0/1 ip mode eigrp 110 md5
R2 interface Serial0/0/1 ip auth mode eigrp 110 md5




R3 interface Serial0/0/1 ip auth mode eigrp 110 md5
R4 interface Serial0/0/1 ip auth mode eigrp 110 md5

Implementing a Secure Update of OSPF and EIGRP Protocol
Attackers will definitely try to gain access into the network through the router devices,
intercepting peering sessions as well as the using the routing information (Davis, 2014). This
kind of attack can be addressed by the use of protocols such as EIGRP, BGP, OSPF, and RIPv2
as they have configurations that help in securing of the routing infrastructure (Halsall, 2016). The
appropriate methods of this situation are:

Neighbor authentication whereby the routing protocols is implemented in a way that
only the router receives will be fed with reliable and appropriate routing information that
comes from trusted neighbors. Such configurations are done through certification of the
authenticity that is applied the entire neighbor as well as integrity of its underlying
routing updates. Therefore, each router should be initially configured to have their shared
secret key which will be used in validation of any routing update occurring. For every
routing update that will be sent, each router within the network will have to sign it by use
of the predefined secret key.
