General Guidelines for Presentation of Academic Work

Magic Tricks is a magic equipment supplying business that consist of 50 employees. The employees are then divided into three departments namely Gadgets, Finance and Sales within the same company. The company needs to set up and establish communicate channel for data and information sharing among the departments. The company also needs an active directory to generate a domain for the administrator and all the employees and also to host a website among others.

Network topology is simply how machine and other communication devices are setup for communication. Ideally it’s the layout of the entire network before the communication commences. On our case study, we will see how all departments are able to interact and share data among themselves. While coming up with the topology, one must study the area in which one is laying up the network and some of the barriers that may lead to unsuccessful layout and software and hardware requirement while setting up. The topology diagram below represents the NetMap in the Simulator to access each of the devices from within the Simulator.

That simply is the physical layout of the three department namely Finance, sales and Gadget. After laying out, the following step focuses on how the devices are configured to communicate within the network.

On configuring the network, there are four steps that should be covered for a complete and successful network [1].

• Configuring the LAN (Local Area Network) which is the Fast Ethernet cable
• Set the WLAN (Wireless Local Area Network), this is majorly among the routers
• Dynamic Routing Protocol by conveying packets though different routes and channels provided the destination of the system in the current condition.
• Verifying our network.

The topology for this lab contains three types of networks: the 10.1.1.4/30 wide area network (WAN) that contains the serial interfaces that connect Router1 and Router2, 10.1.1.7/30 that is established in Router2 and 10.1.1.9 from Router3 and the 192.168.100.0/24 local area network (LAN) that connects PC1, PC2 and PC3 to the FastEthernet 0/0 interface of Router1. The 192.168.200.0/24 LAN connects PC4, PC5 and PC 6 to the FastEthernet 0/0 interface of Router2 and the 192.168.300.0/24 LAN that connects PC, PC7, PC8 and PC9 to the FastEthernet 0/0 interface of Router3. Enhanced Interior Gateway Routing Protocol (EIGRP) is used to exchange routing table updates between the Routers in the network [2] .

Starting with WAN, there is a basic step to step procedure that is needed to be abided with while setting up. First on Router 1, you should issure the following command

Router>enable

Router#configure terminal

Router(config)#hostname Router1

The following command should be administered for the serial0/0 interface to configure ip address, subneting and clocking

Router1(config)#interface serial 0/0

Router1(config-if)#ip address 10.1.1.5 255.255.255.252

The Business Case

Router1(config-if)#clock rate 64000

you should issue the following commands to examine the Serial 0/0 interface

Router1(config-if)#exit

Router1(config)#exit

Router1#show ip interface brief

Interface	IP Addresses	OK	Method	Status	Protocol
Serial0/0	10.1.1.5	Yes	Unset	administratively down	Down
Serial0/1	Unassigned	Yes	Unset	administratively down	Down
Fastethernet0/0	Unassigned	Yes	Unset	administratively down	Down
Fastehternet0/1	Unassigned	Yes	unset	administratively down	Down

Router1#configure terminal

Router1(config)#interface serial 0/0

Router1(config-if)#no shutdown

Back to router 1 after configuring the serial0/0 and the rest of the router, we go down to the switches, that’s the fastEthernt 0/0 interface. One should use the followint ip addresses and subnetmasks

Router1#configure terminal

Router1(config)#interface fastethernet 0/0

Router1(config-if)#ip address 192.168.100.1 255.255.255.0

you should issue the following commands to examine the fastethernet 0/0 interface

Router1(config-if)#exit

Router1(config)#exit

Router1#show ip interface brief

Interface	IP Addresses	OK	Method	Status	Protocol
Serial10/0	10.1.1.5	Yes	Unset	up	up
Serial10/1	Unassigned	Yes	Unset	administratively down	Down
Fastethernet0/0	192.168.100.1	Yes	Unset	administratively down	Down
Fastehternet0/1	Unassigned	Yes	unset	administratively down	Down

RouterA#configure terminal

RouterA(config)#interface fastethernet 0/0

RouterA(config-if)#no shutdown

	Router1	Router2	Router3
Serial 0/0	192.168.100.1	192.200.1.	192.168.254.1

Upon setting up the corresponding ip addresses for th pcs the follow criteria needs to be followed

You should issue the following commands to configure the IP address and default gateway for each PC and the other Router1sponding machines: On PC1:

C:>ipconfig /ip 192.168.100.2 255.255.255.0

C:>ipconfig /dg 192.168.100.1

From the router, one can run the following command to check if the ping is succesfull.

C:>ping 192.168.10.1

Pinging 192.168.10.1 with 32 bytes of data:

Reply from 192.168.10.1: bytes=32 time=56ms TTL=241

Reply from 192.168.10.1: bytes=32 time=54ms TTL=241

Reply from 192.168.10.1: bytes=32 time=60ms TTL=241

Reply from 192.168.10.1: bytes=32 time=68ms TTL=241

Reply from 192.168.10.1: bytes=32 time=50ms TTL=241

Ping statistics for 192.168.10.1:      

Packets: Sent = 5, Received = 5, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:      

Minimum = 50ms, Maximum =  68ms, Average =  58ms

After completion of successful network configuration, the next step is to configure the WAN interface to the routers for ideal communication of the routers.

To kick off this process, we will start with router1 to detect the amount of frame relays from Router 1 to Router 2. The following criteria should be used.

Router1(config-if)#interface serial 0/0

Router1(config-if)#encapsulation frame-relay

Router1(config-if)#no shutdown

Router1(config-if)#interface serial 0/0.1 point-to-point

Router1(config-subif)#ip address 10.1.1.1 255.255.255.252

Router1(config-subif)#frame-relay interface-dlci 102

Configuring a WAN interface on a router should follow the command below

Router1(config-if)#interface serial 0/0

Router1(config-if)#encapsulation frame-relay

Router1(config-if)#no shutdown

Router2(config-if)#interface serial 0/0

Router2(config-if)#encapsulation frame-relay

Router2(config-if)#no shutdown

Router3(config-if)#interface serial 0/0

Router3(config-if)#encapsulation frame-relay

Router3(config-if)#no shutdown

Router1(config-if)#interface serial 0/0.2 point-to-point

Router1(config-subif)#ip address 10.1.1.1 255.255.255.252

Router1(config-subif)#frame-relay interface-dlci 102

Router1(config-subif)#interface serial 0/0.3 point-to-point

Router1(config-subif)#ip address 10.1.1.5 255.255.255.252

Router1(config-subif)#frame-relay interface-dlci 103

Router2(config-if)#interface serial 0/0.1 point-to-point

Router2(config-subif)#ip address 10.1.1.2 255.255.255.252

Router2(config-subif)#frame-relay interface-dlci 201

Router2(config-subif)#interface serial 0/0.3 point-to-point

Router2(config-subif)#ip address 10.1.1.13 255.255.255.252

Router2(config-subif)#frame-relay interface-dlci 203

Router3(config-if)#interface serial 0/0.1 point-to-point

Router3(config-subif)#ip address 10.1.1.6 255.255.255.252

Router3(config-subif)#frame-relay interface-dlci 301

Router3(config-subif)#interface serial 0/0.2 point-to-point

Router3(config-subif)#ip address 10.1.1.14 255.255.255.252

Router3(config-subif)#frame-relay interface-dlci 302

This is a sample of the result displayed in the above command of both Router 2 and Router 3

Network Topology

Router2(config-subif)#end

Router2#show controllers serial 0/1

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0

buffer size 1524  HD unit 0,V.35 DTE cable

cpb = 0x7, eda = 0x58DC, cda = 0x58F0

RX ring with 16 entries at 0x4075800

00 bd_ptr=0x5800 pak=0x1B5E24 ds=0x4079108 status=80 pak_size=13

01 bd_ptr=0x5814 pak=0x1B85B8 ds=0x4080384 status=80 pak_size=13

Router3(config-if)#end

Router3#show controllers serial 0/1

HD unit 0, idb = 0x1AE828, driver structure at 0x1B4BA0

buffer size 1524  HD unit 0,V.35 DCE cable

cpb = 0x7, eda = 0x58DC, cda = 0x58F0

RX ring with 16 entries at 0x4075800

00 bd_ptr=0x5800 pak=0x1B5E24 ds=0x4079108 status=80 pak_size=13

01 bd_ptr=0x5814 pak=0x1B85B8 ds=0x4080384 status=80 pak_size=13

The following command should be addressed to configure the appropriate ip addresses for router 2 and router 3 serial interface 0/1 to enable the interface of the apporpriate device and the clock rate of 100kbps on Router 3

Router2#configure terminal

Router2(config)#interface serial 0/1

Router2(config-if)#ip address 10.1.1.5 255.255.255.252

Router2(config-if)#no shutdown

Router3#configure terminal

Router3(config)#interface serial 0/1

Router3(config-if)#ip address 10.1.1.6 255.255.255.252

Router3(config-if)#clock rate 1000000 Router4(config-if)#no shutdown

You should verify your configuration by issuing a ping from Router3 to the WAN interface of each of the other routers (Router 1: 10.1.1.5; Router2: 10.1.1.7; Router3: 10.1.1.9). The pings should be successful:

Router3(config-if)#end

Router3#ping 10.1.1.10

Router3#ping 10.1.1.8

Router3#ping 10.1.1.6

On our last step is configuring EIGRP Dynamic Routing on the Routers. One should Ping from PC1 to PC2 (192.168.100.2), PC3 (192.168.100.4) and PC4 (192.168.100.3). PC4 fails because Router 1 does not have a route to the remote networks. And also across the entire network

C:>ping 192.168.100.2

C:>ping 192.168.100.4

C:>ping 192.168.100.3

You should issue the following commands to configure an EIGRP process on all three routers using an autonomous system number (ASN) of 100and to configure EIGRP to announce all networks that are directly connected to the routers specifying each subnet:

Router1(config-subif)#exit Core(config)#router eigrp 100

Router1(config-router)#network 10.1.1.0 0.0.0.3

Router1(config-router)#network 10.1.1.4 0.0.0.3

Router1(config-router)#network 192.168.100.0 0.0.0.255

Router2(config-subif)#exit

Router2(config)#router eigrp 100

Router2(config-router)#network 10.1.1.0 0.0.0.3

Router2(config-router)#network 10.1.1.12 0.0.0.3

Router2(config-router)#network 192.168.100.0 0.0.0.255

Router3#configure terminal

Router3(config)#router eigrp 100

Router3(config-router)#network 10.1.1.4 0.0.0.3

Router3(config-router)#network 10.1.1.12 0.0.0.3

Router3(config-router)#network 10.1.1.4 0.0.0.3

Router3(config-router)#network 192.168.254.0 0.0.0.255

The last step is to verify the network connectivity to ensure that everthings is in to place to commence the start of communication channel between the three depatments.

Conclusion

In conclusion, we are able to say that the netwrok is able to meet different criteria reqired for the planning design and configuration of the netwrok devices in the region. Magic Tricks is able to implement the network on the three depatments for data transmission and resorce sharing will be successfull.
