Step 1: Connect the equipment

1. Connect Router1 to Router2 and Router3 using serial cables.
2. Connect Router2 to Router3 using serial cables.
3. Connect a PC with a console cable to perform configurations on the routers.

Step 2: Perform basic configurations on the routers

1. Establish a console session with Router1 and configure hostname, passwords, and interfaces as described in the table. Save the configuration.
2. Establish a console session with Router2 and perform a similar configuration, using the addresses and other information from the table. Save the configuration.
3. Establish a console session with Router3. Configure hostname, passwords, and interfaces according to the table. Save the configuration.

Step 3: Configure EIGRP routing with default commands

1. On Gateway, configure EIGRP as the routing protocol with an autonomous system number of 100, and advertise the appropriate networks.

Gateway(config)#router eigrp 100
Gateway(config-router)#network 10.0.0.0
Gateway(config-router)#network 10.0.0.4
Predict: How will EIGRP report these subnets in the routing table?
Step 4: Configure MD5 Authentication

1. Create a keychain named discchain.
2. Configure a key 1 that has a key string of san-fran.
3. Enable the workgroup router to utilize EIGRP MD5 authentication with each of your EIGRPneighbors and to use the keychain icndchain.

Step 5: Reflection

1. What is the importance of enabling authentication on the routing updates?

1. Connect Router1 to Router2 and Router3 using serial cables.
2. Connect Router2 to Router3 using serial cables.
3. Connect a PC with a console cable to perform configurations on the routers.

1. Establish a console session with Router1 and configure hostname, passwords, and interfaces as described in the table. Save the configuration.
2. Establish a console session with Router2 and perform a similar configuration, using the addresses and other information from the table. Save the configuration.
3. Establish a console session with Router3. Configure hostname, passwords, and interfaces according to the table. Save the configuration.
