Subnet 200.25.11.0/24 to address the network topology depicted in Figure 1. Use the most efficient addressing possible. You have to present your stepwise solution with justification. Showing just the final subnets assignment will not be accepted. B. You have decided to add a new serial link between Bldg1 and NY routers. What do you need to do to address the newly created network between the two routers? Figure 1 [15 marks] Part 2: Dijkstra’s Shortest Path First Algorithm Figure 2 shows a network with nodes ‘a’ to ‘f’ (these are shown circled) with the indicated link costs, use Dijkstra’s algorithm to compute the least cost path from node ‘a’ to all network nodes. Show how the algorithm works by computing a Link-state (LS) table. Then show the least cost path and the forwarding table for source node ‘a’. You have to present a stepwise solution supplemented with proper justification. Showing the final results only will not be accepted. Figure 2 [15 marks] Part 3: Network Configuration Consider the following network topology depicted in Figure 3 and implemented in CW.pkt file. As a network engineer, you have been requested to accomplish tasks {A, B, C, D, E, F, G, H, and I} listed below. You need to configure the network in the supplemented file ‘CW.pkt’ according to these tasks while providing a detailed justification for each one in your report. You are not supposed to change the configuration of any end-device, i.e., a workstation, a server, or an IP-Phone unless you are clearly requested to do so. Tasks to be undertaken: In this coursework, you are expected to answer a set of questions (Part 1 and Part 2) and configure a given network topology ‘CW.pkt’ according to a list of tasks (Part 3). You need to provide detailed stepwise justification for all parts in your report. Posting final results or configurations without proper explanation that can reflect your understanding will not be marked. Figure 3 [A clearer figure is provided in the supplemented file ‘CW.pkt’] A. Following the network labels, configure all of the routers’ serial interfaces with DCE and DTE ends set to .1 and .2 IP addresses respectively. Clock rates have to be configured according to Table 1. Note: In your report, including justification for a single serial link configuration will be sufficient. Table 1 [5 marks] B. All web servers on the Internet is approachable only via their public IP addresses as registered on Google Public DNS Server (already provided in file ‘CW.pkt’). Their private IP addresses are not routable and should not be disclosed to public. Configure their gateways to enforce this rule. Hint: use NAT.[5 marks] C. Configure RIPv2 in the red-circled area.[5 marks] D. Configure Multiarea OSPF {area 0, area 1, and area 2} giving proper route summarization, correct cost information, and router-id(s) if needed.[10 marks] ( Area Clock Rate OSPF Backbone Area 2000000 OSPF Area 1, Area 2 and RIPv2 Area 128000 Links to organizations A and B 64000 ) E. Redistribute RIPv2 updates into OSPF and vice versa.[5 marks] F. Configure all of the devices in Organization A. Router 1 should act as a DHCP server for all of the workstations and IP Phones. They should all get private, unrouteable IP addresses as per the depicted network labels. PCs should be able to access the Internet via BT-ISP. IP-Phones should be allocated the following numbers depicted in Table 2: Table 2 Phone Number IP Phone1 1001 IP Phone2 1002 IP Phone3 1003 Repeat the same for Organization B with IP-Phones allocated numbers shown in Table 3. Note: Justification is not required for Organisation B. Table 3 Phone Number IP Phone4 2001 IP Phone5 2002 IP Phone6 2003 [10 marks] G. Enable telephone communication between Organization A and B. Hint: configure a dial-peer. [5 marks] H. Microsoft has decided to offer its own public DNS service. For that, the topology is updated according to Figure 4. Update the topology and the configuration of ‘CW.pkt’ file so that the newly created Microsoft Public DNS Server is reachable using its public IP address 11.3.3.3. Do you notice any issues in the network? If yes, discuss how to solve them.[10 marks] Figure 4 I. Google has decided to create a server farm in order to serve more customers. Consider the update depicted in Figure 5, how would you use NAT to implement load-balancing across the server farm? Note: The required configuration is not currently supported by Cisco Packet Tracer, you just need to figure it out manually in your report with proper justification just like other tasks. [10 marks] Figure 5 Report presentation: organization, readability, etc.[5 marks] Deliverables to be submitted for assessment: 1. A written document consisting of three parts, with answers to each question provided as a separate item (max. 3000 words excluding words in figures). Detailed answers and stepwise justification/explanation should be given for each question/task to reflect your understanding. The mark will not be awarded unless the justification is provided and is unique according to Turnitin. 2. A .pkt file, preferably entitled according to your student number, e.g., P12056142.pkt, and configured according to the tasks of Part 3 (excluding task I). Note: Do not forget to provide the requested stepwise justification for every task in Part 3 in your report.
