4 Before establishing the L2TP tunnel, you must first establish an ATM link between
the OCR 812 and the Cisco router. To establish an ATM link, install an ATM
interface card in the router and configure the card using the commands specified
in step b.
a To install an ATM interface card in your Cisco router, please refer to the
instructions provided by your interface card manufacturer.
b To configure an installed ATM interface card, enter the following commands:
interface atm 2/0

5 Once the L2TP tunnel has been established (and authentication has been
successful), the following Virtual Template will assign an IP address for the defined
L2TP pool:
