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?
