Configuring Demand Routing for Primary ISDN Modules
Using Demand Routing for ISDN Connections
8-24
Like loopback interfaces, demand interfaces do not have to be activated. That
is, you do not have to enter no shutdown. After you create the demand
interface, its status automatically changes to administratively up. The demand
interface will begin spoofing an up status after you configure an IP address
for it.
Shut Down the Demand Interface. You may need to shut down the
demand interface. For example, you may need to shut down the interface to
correct a configuration setting or to troubleshoot a problem with the ISDN
line. Enter:
ProCurve(config-demand 1)# shutdown
To activate the interface again, enter:
ProCurve(config-demand 1)# no shutdown
Configuring an IP Address
Because the demand interface uses PPP as the Date Link Layer protocol, you
have several options for setting up an IP address: you can assign the demand
interface a static IP address, you can configure it to negotiate the IP address
from its PPP peer, or you can configure it as an unnumbered interface.
Configure a Static IP Address. To assign the demand interface a static IP
address, enter:
Syntax: ip address <A.B.C.D> <subnet mask | /prefix length>
For example, you might enter:
ProCurve(config-demand 1)# ip address 10.10.10.1 255.255.255.252
or
ProCurve(config-demand 1)# ip address 10.1.1.1 /30
Configure a Negotiated IP Address. If you want the demand interface to
negotiate an IP address with its PPP peer, enter the following command from
the demand interface configuration mode context:
Syntax: ip address negotiated
