Creating The Demand Interface - HP ProCurve 7000dl Series Basic Management And Configuration Manual

When the ProCurve Secure Router detects traffic that must be routed through
a demand interface, it processes the extended ACL applied to the demand
interface to define the interesting traffic. If the traffic matches that ACL, the
router attempts to establish the ISDN connection.
After the physical ISDN connection is established, the ProCurve Secure
Router uses PPP to set up the Data Link Layer. To ensure that only authorized
routers establish ISDN connections to your router, you should configure PPP
authentication for the dial-up connection.
To configure the demand interface, complete the following steps:
1. Create a demand interface.
2. Configure an IP address for the demand interface.
3. Apply the ACL that defines interesting traffic to the demand interface.
4. Specify whether the demand interface can originate a call, answer a call,
or both.
5. Create a resource pool.
6. Configure instructions for placing a call by entering connect-sequence
commands.
7. Configure timers, caller, and hold queue settings (optional).
8. Configure caller settings (optional).
9. Configure PPP authentication (optional but recommended).
You must complete steps 1-6. Steps 7-9 are optional.

Creating the Demand Interface

To create a demand interface and access the demand interface configuration
mode context, enter the following command from the global configuration
mode context:
Syntax: interface demand <number>
Replace <number> with a number between 1 and 1024 for this demand
interface. You should configure a different demand interface for each connec-
tion to a remote site or device, and each demand interface must have a unique
number.
