Learning Objectives

Upon completion of this lab, you will be able to:

• Subnet an address space with given requirements

• Assign appropriate addresses to interfaces and document them in the address table below

• Cable the network according to the diagram

• Erase the startup configuration and reload a router to the default state.

• Configure EIGRP routing on all routers.

• Configure and propagate a default static route.

• Verify EIGRP operation.

• Test and verify full connectivity.

• Reflect upon and document the network implementation.

Scenario

In this lab, you will be given a summarized address which you will use to create an efficient addressing scheme to accommodate all hosts on the network. A combination of EIGRP and a static default route will be

required so that hosts on networks not directly connected can communicate. You have completed this lab when each host can ping the each other.

Task 1: Create an Addressing Scheme.

Step 1: Use the 192.168.156.0/22 address to create an addressing scheme to accommodate all hosts on the network. Begin the address assignments with the 192.168.157.0 address.

Document all subnet addresses in Table 1.

Task 2: Configure EIGRP with Process ID 1 using Wildcard Masks.

Step 1: Configure EIGRP on the HQ router and advertise all directly connected networks except the loopback interface.

Advertise the network along with a wildcard mask for the appropriate subnet.

Step 2: Configure EIGRP on the Remote1 router and advertise all directly connected networks.

Advertise the network along with a wildcard mask for the appropriate subnet.

Step 3: Configure EIGRP on the Remote2.

Advertise the network along with a wildcard mask for the appropriate subnet.

Task 3: Discontiguous Networks.

Step 1: Configure each router so that subnet mask information about each network is propagated within the EIGRP updates.

Step 2: Verify that each router has a path to each network in the autonomous system.

Task 4: Static Default Route

Step 1: Configure a static default route on the HQ router to the loopback interface.

ip route 0.0.0.0 0.0.0.0 loopback0

Step 2: Propagate the static default route in the HQ routing update.
