Executive Summary
We are going to discuss different methods available for implementing a virtual network to
check the connectivity. We will then check the connection between each device by assigning
the address to each. Then we will configure some of the services related to the server like Web,
DHCP and also DNS. Lastly, we will try to implement a firewall to block web service for a single
user connected to the network.

Task 1
For the designing of the network, there are different methods which we can make use of. Some
of the methods for implementing the network are:
1. Packet Tracer of Cisco,
2. GNS 3,
3. NetSim.
These are some of the software which is widely used for designing a virtual network. Each of
the software has some benefits as well as there are some drawbacks of using them. We are
going to discuss the drawbacks and the benefits of each software mentioned above:
1. Packet Tracer:
Figure 1: Packet Tracer
Some boons of packet tracer are:
 Implementation of the network which is small is very easy.
 Its SIM mode is one of the best advantages.

Sai Ramya Krishna Yerubandi 11621960

 The user can easily check the configuration of the network.
 It supports the simulation mode.
Some drawbacks of packet tracer are:
 Debugging is not supported by the packets of OSPF.
 STP port gets affected very easily.
 EtherChannel is not accepted by the switches.
2. GNS 3
Figure 2: GNS 3
Some Boons of GNS 3 are:
 Load balancing is supported in GNS 3.
 It is basically free of loops.
 The understanding and the implementation of the network is very easy.
Some Drawbacks of GNS 3 are:
 The large network takes a long time to get converge.
 It is very inefficient with regards to the intense bandwidth.

Sai Ramya Krishna Yerubandi 11621960

 The load balancing is supported only for the equal-cost of the given load
balancing.
3. NetSim:
Figure 3: NetSim
Source: (Boson, 2019)
Some boons of NetSim are:
 The analysis of What-If is performed easily.
 It easily finds out the system behaviour.
 While comparing with the analytical model, the result is so accurate (Harry,
2010).
Some drawbacks of NetSim are:
 Some of the time the interpretation of the result of the simulation is difficult.
 Simulation conduction is very expensive.
We are going to use Packet Tracer for building up the network. The following configuration
whichever is needed for this network will be done using packet tracer itself.

Task 2
Now, we need to design and implement the network. The network will be implemented as per
the requirement. The requirement is like that the Computers will be connected to the switch
and switch will be connected to the router and the router will be connected to the different
router after which that router will be connected to the switch and lastly the switch will be used
to connect the server or many servers. The network will be like as shown in the image below:
Figure 4: Network Design
We have designed the network as per the requirement. Now we need to configure the network
so that the communication will be done in between the clients and the server.
1.
We first need to configure the interfaces of the networking devices. For the interface of
the computers, we will use the address of 163.60.1.2 255.255.0.0.

Figure 5: Computer Interface
After this, we will configure the interface of the router. So, there will be two different interfaces
which will have two different networks. The first address will be 163.60.1.1 255.255.0.0 and the
next one will be 10.0.0.1 255.0.0.0.

Figure 6: Router Interface
Then lastly, we will configure the address of the server which is connected in the network. The
address for the server will follow 163.61.1.3 255.255.0.0.

Figure 7: Server Interface
The first thing which has to be done after the designing and connectivity of the networking
devices is the IP addressing of each of the connected devices. The networking devices which all
are connected in the given network has been assigned the IP addresses. This will help to
communicate with other networking devices.
2. Now we need to configure routing in between two different routers so that the different
network will be able to communicate with each other.
We will configure RIP for these routers. Each will have a different network to configure.
As per Router 1, the configuration will be:

Sai Ramya Krishna Yerubandi 11621960

Figure 8: RIP Configuration of R1
This includes the network address of that network which is connected to its own interface. The
two networks which are connected to its own interface is 163.60.1.0 and 10.0.0.0.
For Router 2 the configuration will be like:
10
Sai Ramya Krishna Yerubandi 11621960

Figure 9: RIP configuration for R2
The configuration of router 2 with RIP will include the network address of those which are
connected to its own interface. The addresses which are connected to its interface are
163.61.1.0 and 10.0.0.0.
After this static routing configuration in the routers, the clients of the different network will be
able to communicate with each other easily.
3. Now we will check the connection of each connected devices. This will be done by
pinging one system with another. First, we will ping client computer with
