Chapter 10. Trouble Tickets: The Sum of All Fears
This final chapter offers you a practical comprehensive troubleshooting review. Part I of this book covers protocol characteristics, methodology, and tools. Part II focuses on supporting the IP and IPX protocols as well as some other interesting topics such as upgrades and password recovery. The focus of Part III is Ethernet, switching, and VLANs. Part IV is about supporting the WAN. I take a slightly different approach in this chapter. In this part, I present you with a new physical scenario and several Trouble Tickets. You first need to discover the topology and get a good baseline. Then you work through the Trouble Tickets on your own one-by-one to spot and fix any issues.
This chapter covers the following topics:
Scenario: Shooting Trouble Review
Trouble Ticket 1 Discovery Lab
Trouble Ticket 2 Documentation Lab
Trouble Ticket 3 OSPF Lab
Trouble Ticket 4 RIP/OSPF/EIGRP Redistribution Lab
Trouble Ticket 5 Frame Relay/ISDN Backup Lab
Trouble Ticket 6 VLAN and Spanning Tree Lab
