Instructor Tips Lab 6.1
Continue using the lab teams for these labs. It is preferable for the labs in this chapter to
be done in one sitting, as the configurations are not saved.
It is important to make sure students do the Chapter 5 labs correctly before going on to
the Chapter 6 labs. You may want to tell them to make sure they can ping up and down
the routers before they start the chapter 6 labs.
