CCNA3 - Lab 5.4.1.4 Implementing EIGRP

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 EIGRP neighbors and to use the keychain icndchain.

Step 5: Reflection

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