Topology

ITNE3007 Assignment

Task 1: Design and Document an Addressing Scheme
Step 1. Design an addressing scheme.
Based on the network requirements shown in the topology in Figure 1, design an appropriate addressing scheme.
· For the LANs, use the address space 10.1.32.0/22. Starting with the largest subnets’ requirements on B1, assign subnets in order throughout the topology.
· For the WANs, use the address space 172.20.0.0/27. Assign WAN subnets according to the following specifications:
o Subnet 0 to the WAN link between HQ and B1
o Subnet 1 to the WAN link between HQ and B2
o Subnet 2 to the WAN link between HQ and B3
o Subnet 3 to the WAN link between B1 and B2
o Subnet 4 to the WAN link between B2 and B3
Step 2. Document the addressing scheme.
· Use the blank spaces on the topology to record the network addresses in dotted decimal/slash format.
· Document the IP addresses, subnet masks, and default gateway addresses:
o For LANs, assign the first address to the router interface. Assign the last address to the PC.
o For WAN links to HQ, assign the first address to the HQ router.
o For WAN links between branch routers:
§ Assign the first address to B1 for the link between B1 and B2.
§ Assign the first address to B2 for the link between B2 and B3.
Task 2: Apply a Basic Configuration
Step 1. Configure the routers.
Using your documentation, configure the routers with basic configurations.
Step 2. Configure the PCs.
Using your documentation, configure the PCs with an IP address, subnet mask, and default gateway.
Task 3: Test Connectivity
Before continuing, make sure that each device can ping its directly connected neighbour.

ITNE3007 Assignment

Task 4: Configure and Verify EIGRP Routing
Step 1. Configure EIGRP.
Configure all devices with EIGRP routing using 1 as the process ID. In your configuration, make sure that you include the following:
· Disable automatic summarization.
· Stop routing updates on interfaces that are not connected to EIGRP neighbours.
· All LANs should be summarized into one advertisement to neighbours. For example, HQ should summarize its two LANs when advertising to B1, B2, and B3.
Step 2. Verify EIGRP.
Use verification commands to check your configuration. All routers should be converged on all the 10.1.32.0/22 and 172.20.0.0/27 subnets.
Task 5: Fine-Tune EIGRP
Step 1. Adjust bandwidth values used to calculate metrics.
The links between the branch routers (B1 to B2 and B2 to B3) are for backup purposes only. Configure the bandwidth values to match the actual bandwidth so that EIGRP does not equal-cost load across the T1 links to HQ and the backup links to the neighbouring branch router.
Step 2. Adjust Hello intervals for the slower links.
Change the Hello intervals for the 64-kbps links to 60 seconds.
Task 6: Configure Static and Default Routing
Because Packet Tracer does not support redistribution of default routes, all routers except ISP will need a default route.
Task 7: Test Connectivity and Examine the Configuration
Test connectivity and examine the configuration.

LAB 2 – OSPF Configuration
Please read the scenario carefully and implement the topology in GNS3. You need to complete all steps to receive full mark in this assignment. Remember that in each step, you need to configure routers or verify the existing configuration on a specific router. For that, you need to take screenshots of your configuration and paste them in your file. Also, if there are any questions in the given task, you should provide your answer along with the attached screenshots.
Remember that all your screenshots should include your student ID as the hostname of router (e.g. Melbourne3-S1234).
Please provide screenshots in a correct order and use headings to specify the respected completed task. This assignment carries 20% weightage in your final result and the due date is 13th of October.
Objective
Upon completion of this lab, you will be able to
· Create an efficient VLSM design given requirements
· Assign appropriate addresses to interfaces and document
· Create a network according to the topology diagram in Figure 2.
· Configure routers including OSPF
· Configure and propagate a static default route
· Verify OSPF operation
· Test and verify full connectivity
· Reflect on and document the network implementation
Scenario
In this lab activity, you will be given a network address that must be subnetted using VLSM to complete the addressing of the network shown in the topology diagram in Figure 2. A combination of OSPF routing and static routing will be required so that hosts on networks that are not directly connected will be able to communicate with each other. An OSPF area ID of 0 and process ID of 1 will be used in all OSPF configurations.
