Do not assume everyone here has access to the workbook so if you need help,
you need to be explicit on the requirements.
I don't understand this paragraph "also authentication is only done on the
frame-relay"
It's this a requirement on the task, that you can't authenticate EIGRP ?
As for issue 2, I would have to lab that one out but I don't have any
equipment at the moment.
