In each lab, you must restore end-to-end IP connectivity from TATEBAYASHI@mjlnet.com to PERRIS_HGW1. This should be tested by pinging PERRIS_HGW1's loopback interface (10.20.10.1) from TATEBAYASHI@mjlnet.com.

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.
