Lab Scenario - Integrating Network Infrastructures

Issue

The organization you work for has recently merged with another organization. A team hasbegun integrating existing systems with a goal of creating a seamless, transparent networkinfrastructure. The head office of the new organization is located in Fort Worth, Texas. YourChief Information Officer has concerns about application security, and has decided that FortWorth will be the only location hosting an accounting server. End-users in Seattle andMinneapolis require some way of accessing the accounting server in Fort Worth.

Background

Seattle and Minneapolis currently have a wide area network connection that operates at 10Mbps. This service is a managed service provided by the XYZ Telecommunications Company.

As a managed service, XYZ owns the Cisco 4500 routers, and is solely responsible for theirconfigurations. Upon request, XYZ will configure the routers with any provided routing oraccess-list filtering. The Cisco 3600 router at Fort Worth is part of a managed network servicecontract, and is also owned by the XYZ Telecommunications Company.

Action Plan

Two Frame Relay links will be added to the existing network infrastructure, creating a fullymeshed, fault-tolerant network. The organization will purchase 3 Cisco 1601 routers to supportthe Frame Relay network. Your task is to design a network configuration that connects theFrame Relay network to the existing corporate networks.

To Complete This Lab

1. Create a logical network diagram outlining your addressing scheme.

2. Create configurations for all three Cisco 1600 series routers.

3. Document any needed changes (using Cisco IOS commands) for the XYZTelecommunications Company routers.

4. Identify the process by which client workstations from Seattle and Minneapolis will connectto the 10.0.0.0 network.

Things to Note

1. All routing taking place between Seattle and Minneapolis is being handled by static routingentries in the Cisco 4500 Series routers. There are no plans to change this routing policy.

2. Workstations in all cities currently have their default gateway set to the Ethernet 0 interfacesof the local XYZ Telecommunications Company-owned Cisco router.

Second, there can be multiple solutions, some better than others.

An third, we're not going to present the solution(s) right now. We want our readers to submit asolution. It's kinda like a contest. Solutions must be received via e-mail prior to May 19. Leigh

Anne Chisholmwill review the solutions and select the best one(s), which will be posted nextmonth. In addition, the winner will receive a copy of the CCIEprep Exam Study Guide.
