Scenario

The multinational company Gargantuan, Inc., from the introduction of this chapter, has had a consultant completely readdress the company. The company has used the private network 10.0.0.0 and has created a very hierarchical addressing structure. Refer to Figure 7-12 to see this addressing scheme.

The addressing of the network was a major project, with all the necessary pitfalls that attend such a major exercise. The network is now stable, and it is time to solve the problems that are being experienced in timeouts and network crashes.

The consultant assured the company that the resolution to the delays was the addressing scheme, but although the network is easier to manage, there has been no change in the congestion on the network. In addition, EIGRP appears to be losing routes from its routing tables, which is adding to the problem.

The consultant was correct: The network needed to be readdressed to allow EIGRP to function effectively. Unfortunately, the company did not read the report carefully and missed the other part of the solution.

1 What needs to be done in addition to solve the problems caused by EIGRP? Give the configuration commands necessary to activate this solution on Router A.

The WAN is a Frame Relay cloud, and Router A is the hub in the hub-and-spoke configuration. Each VC is 56 kbps.

2 Give the commands to configure Router A for EIGRP over this NBMA cloud.

3 Give the commands to configure Router B for EIGRP over this NBMA cloud.
