Troubleshooting Demand Routing
After you configure demand routing, you should test your configuration to
ensure that it is working correctly. Is the right traffic triggering the connection,
and can the BRI interface successfully establish a connection to the far-end
router? Are your settings for the idle-timeout and the fast-idle sufficient for
your WAN environment?

Checking the Demand Interface

The first step you should take to check your configuration is also the first step
you should take to troubleshoot demand routing. You should ensure that the
demand interface and its associated BRI interfaces are ready to make a
connection.
Use the show interfaces demand command to view the status of the demand
interface, which should be up (spoofing). If the demand interface is down,
ensure that you have assigned it a valid IP address. If you configured the
demand interface as an unnumbered interface, make sure that the interface
with the actual IP address is up.
If the demand interface went down because it could not establish a connection
during the recovery mode, its status will be down (recovery failed). In this
case, you must identify the problem causing the failure and then you must
clear the connection so that the status of the demand interface returns to up
(spoofing). Until then, the demand interface cannot establish an ISDN
connection.
To clear the ISDN connection, shut down the demand interface. From the
demand interface configuration mode context, enter:
ProCurve(config-demand 1)# shutdown
To re-activate the interface, enter:
ProCurve(config-demand 1)# no shutdown
