Part 1 (70 Marks) Create an approach for network address implementation and testing

Research question (RQ1):

If layered network reference models are applied to implementing the network of routers and switches and end devices does this assist the network engineer?

Figure 1Venuestream Network

1.1 Perform a literature search relating to the research question above (RQ1) and document the results of your relevant literature in a bibliography.

1.2 Write a review of the important literature you have identified in the literature search in 1.1.

1.3 Formulate an approach for documenting, implementing and testing the network addressing of the computer network in figure 1 show and describe this approach appropriately in your assessment submission.

1.4 Rigorously justify the use of this approach for implementing and testing the network addressing of the computer network in figure 1 by writing a justification in the report.

According to the Cisco Netacad Introduction to Networks module

·  3.2.4.1 The Benefits of Using a Layered Model

The benefits to using a layered network reference model to describe network protocols and operations include:

• Assisting in protocol design because protocols that operate at a specific layer have defined information that they act upon and a defined interface to the layers above and below.

• Fostering competition because products from different vendors can work together.

• Preventing technology or capability changes in one layer from affecting other layers above and below.

• Providing a common language to describe networking functions and capabilities.

Cisco do not provide any evidence in the form of research with primary or reference to secondary data to justify these statements in section 3.4.2.1 (Cisco Netacad).

Therefore you should identify quality literature sources which include the topic of the main network reference models by performing a literature search using the Solent Library and academic sources.

Specify and use a criterion to exclude sources which are not relevant to the research question.

Write a literature review of up to 20 quality literature sources of information you have found about network reference models.

Reference the sources you have reviewed in a bibliography using the Solent Harvard method of referencing.

Formulate an approach for implementing and testing the network addressing of the computer network in figure 1. The approach may take the form of an original diagram or table or narrative which you have created yourself.    

Describe, explain and justify this approach by analyzing findings from the literature review performed.

Part 2 (30 marks) Complete the IPv6 Addressing of the Computer Network

For the network topology in figure 1 you must design an IPv6 Addressing scheme and complete the documentation by completing the following tables. The network is classed as one site and is allocated the following IPv6 address Global Routing Prefix

2001:DB8:ACAD::/48

·  7.2.4.1 Structure of an IPv6 Global Unicast Address  (Cisco Netacad)

Figure 2 Structure of an IPv6 address

Your first task is to calculate and allocate 4 IPv6 subnets by appending a subnet ID to the Global Routing Prefix you have been given and to document the IPv6 subnets in the table below

To calculate your first Subnet ID convert the last 4 Decimal numbers of your student number into a 4 digit hexadecimal number (16 bits) and use them as the 1^st Subnet ID in the table in Figure 3 below

For example if your student number is 16777215  in decimal

The last 4 decimal digits are 7215

your subnet ID will be 1c2f in hexadecimal

Write Your Subnet ID in Hexadecimal ………………..

Allocate consecutive IPv6 Subnet IDs to the following 4 subnetworks for the HQ and Branch LANs starting at your calculated subnet ID and incrementing each new subnet ID by 1 (adding 1).

Write all IPv6 addresses in the compressed format following the rules to help reduce the notation.

·  7.2.2.2 Rule 1 – Omit Leading 0s

·  7.2.2.3 Rule 2 – Omit All 0 Segments

Hosts’ IPv6 addresses and Network Interfaces’ IPv6 interface IDs must be allocated using IEEE EUI-64 standard.

·  7.2.4.5 EUI-64 Process and Randomly Generated

Choose an appropriate prefix length for IEEE EUI-64

·  7.2.3.2 IPv6 Prefix Length

Subnet Description	Subnet Id	IPv6 Network Prefix /Prefix Length
HQ LAN1
HQ LAN 2
Branch IoT LAN
Branch CCTV LAN

Figure 3 IPv6 Subnet Addresses

Document the Global unicast IPv6 addresses to the network interfaces of the Router devices in the Interface Address table in Figure 4 using the MAC addresses given in the table.

All IPv6 addresses  are configured as EUI-64 all addresses should be written in the compressed format.

The following is an example of configuration of EUI-64 IPv6 addresses for subnet ID 0000 :

HQ(config-if)# interface g0/0

HQ(config-if)# ipv6 address 2001:db8:acad::/64 eui-64

Document the IPv6 Link Local addresses of the LAN network Interfaces of the router devices by completing the table Link Local address column.

All addresses should be written in the compressed format.

Figure 4 IPv6 Interface address table

For end devices such as PCs and IOT devices, IPv6 addresses will be allocated automatically using IEEE EUI-64 standard. 

Complete the Device address table in Figure 5 with Device IPv6 Address and Address Prefix Length and Link Local address of the End Devices using the MAC addresses given in the table. All IPv6 addresses should be written in the compressed format.
