ITNE3007 Advanced Routing

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 addressingscheme.
• For the LANs, use the address space 10.1.32.0/22. Starting with the largest subnets’ requirementson 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 thefollowing 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/slashformat.
• 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 thePC.
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.

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

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.
