Troubleshooting Practice Labs
The following labs are provided to help you to consolidate and to practice the knowledge and skills that you have gained in this chapter.
Three labs are provided, and all are based on the network topology shown in Figure 2-45.
In each lab, you must restore end-to-end IP connectivity from [email protected] to PERRIS_HGW1. This should be tested by pinging PERRIS_HGW1's loopback interface (10.20.10.1) from [email protected].
Base configurations for the labs can be found on the Cisco Press Web site (www.ciscopress.com/1587051044). Detailed instructions for loading these base configurations onto your lab routers, as well as solutions can be found in Appendix B.
