Configuring Ppp For The Demand Interface - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Using the Web Browser Interface for Basic Configuration Tasks
Configuring Demand Routing for a Primary or Backup Connection
14-98
12. Select Interface Recovery to enable recovery mode if the ProCurve Secure
Router is unable to establish a demand routing connection.
13. In the Interface Recovery Retry Interval, enter the number of seconds
that the router should wait between connection attempts (during recovery
mode).
14. If you want, customize the Demand Hold Queue and Demand Hold Queue
Timeout settings for your environment. The router uses the hold queue
when it receives interesting traffic but that demand-routing connection is
not currently established.
15. If you want, customize the Idle Timeout and Fast Idle Timeout settings
for your environment.
The Idle Timeout setting determines how long the line must remain idle
before the router disconnects the ISDN or analog call.
The Fast Idle Timeout setting is used if a BRI interface or an analog
interface is in contention. That is, if the BRI or analog interface is currently
in use and the router needs to establish another connection using that
interface, the router places the interface in "fast idle timeout." This
decreases the time that the line must be idle before the router can
disconnect the call, thus freeing up the resource for the other connection.
16. In the Match-Interesting Traffic section, select the ACL that defines the
interesting traffic, select the matching logic, and apply it to incoming or
outgoing traffic, or both.

Configuring PPP for the Demand Interface

17. In the PPP Configuration section, configure sent and peer authentication
as needed to prevent an unauthorized peer from trying to connect to your
ProCurve Secure Router.
