Activating The Ppp Interface; Binding The Physical Interface To The Logical Interface - HP ProCurve 7000dl Series Basic Management And Configuration Manual

For example, you would enter the following commands to configure a loop-
back interface and then configure the PPP 1 interface to use the IP address
assigned to that loopback interface:
ProCurve(config)# interface loopback 1
ProCurve(config-loop 1)# ip address 10.1.2.2 /30
ProCurve(config-loop 1)# interface ppp 1
ProCurve(config-ppp 1)# ip unnumbered loopback 1
You do not have to enter no shutdown to activate a loopback interface. The
status of a loopback interface changes to up after you enter the interface
loopback <interface number> command.

Activating the PPP Interface

To activate the PPP interface, enter the following command from the PPP
interface configuration mode context:
ProCurve(config-ppp 1)# no shutdown
Although the PPP interface is activated, its status will not change to up until
it is bound to a physical interface. It can then begin to negotiate a PPP session
with its peer, and if that negotiation is successful, the status of the PPP
interface will change to up.

Binding the Physical Interface to the Logical Interface

On the ProCurve Secure Router, you must bind the physical interface to the
logical interface so that the router knows which Data Link Layer protocol to
use for that WAN connection. When you bind a physical interface to a logical
interface, the two are considered a single interface bind group.
From the global configuration mode context, enter:
Syntax: bind <bind number> <physical interface> <slot>/<port> [<tdm-group
number>] <logical interface> <logical interface number>
You can also enter this command from the PPP interface configuration mode
context.
Replace <bind number> with a number that is globally significant. That is,
each bind command you enter on the router must have a unique bind number.
