What information is necessary?

The wizard will prompt you for the necessary information on a step-by-step
basis. If possible, however, you should have it available before launching the
wizard.
To explain the significance of the information requested by the wizard, we will
be using a typical deployment as an example: setting up a link between a
branch office and its headquarters. The routers involved are named
'HEAD_OFFICE' and 'BRANCH'.
Please refer to the following tables for the entries to be made for each of the
routers. Arrows mark the dependencies between the entries.
