Hello Lawrence,
>> Is authentication a must configure?
no but both sides need to agree on this
what is the PVC state
use sh frame-rel pvc
if it is fine you can
shut the interface
term mon
debug ppp neg
debug ppp auth
no shut serial interface
so you can see if PPP frames flow on the PVC
Hope to help

Lawrence,
Is the virtual template applied to a physical interface/subinterface as suggested in the following document?

Hello Lawrence,
sorry for the basic question:
have you configured for PPP the other side at the remote end of the FR PVC ?
you can troubleshoot how PPP behaves using
debug ppp negotiation
debug ppp authentication
Hope to help
