Kim,
PPPoA is one of those infamous configurations in which the order
of operations is significant. Make sure that you create the
virtual-template or dialer interface *before* you bind it to the ATM VC.
If you just copied and pasted the config most likely the virtual
interface was bound before it was created. As for the dialer or
virtual-template that is only locally significant. The encapsulation
must match on both ends of the link however.
HTH,
