Background/Scenario

In this activity, you will modify the EIGRP metric formula to cause a change in the topology. This allows you to see how EIGRP reacts when a neighbor goes down due to unforeseen circumstances. You will then use the debug command to view topology changes and how the DUAL Finite State Machine determines successor and feasible successor paths to re-converge the network.
