Which details are necessary?
The Wizard requests you for all of the necessary details step by step. If possi-
ble, you should have all of this information to hand before you start the Wiz-

The significance of the information required by the Wizard can be explained
by an example: Connectivity between a branch office and your main office.
The two routers are named 'MAIN OFFICE' and 'BRANCH OFFICE'.
The following tables indicate which entries are to be made for each of the two
routers. Paths show how the entries relate to one another.
