Caller ID Options for ISDN BRI Backup Modules (Optional)
The ProCurve Secure Router accepts ISDN calls based on whether the incom-
ing call's caller id matches a list of acceptable caller ids. You can override an
incoming call's caller id using the caller-id override option. Enter:
Syntax: caller-id override [always | if-no-cid] [<number>]
Replace <number> with the phone number that you want to use to override
the incoming caller id number. The always option replaces all incoming caller
ids with the number you specify. The if-no-cid option uses the specified
number only when an incoming call does not have a caller id.
Configuring a Floating Static Route for the Demand
Interface
As explained earlier, the demand interface spoofs an up status, allowing you
to create static routes to the far-end network connected through the dial-up
interface. For backup connections, you create a floating static route, which is
activated only when the primary route is not available.
To configure a floating static route to the far-end network, you must enter the
following information:
destination address and subnet mask
next-hop address or forwarding interface
administrative distance
To configure an IP route, enter the following command from the global
configuration mode context:
Syntax: ip route <destination A.B.C.D> <subnet mask | /prefix length> <next hop
A.B.C.D | forwarding interface ID> [<administrative distance>]
For example, to configure a route to network 192.168.7.0 /24 through demand
interface 1 and assign this route an administrative distance of 2, enter:
ProCurve(config)# ip route 192.168.7.0 /24 demand 1 2
This route appears in the routing table only if another route with a lower
administrative distance is not available. For example, Figure 3-10 shows the
routing table for a network if the primary WAN connection to network
192.168.7.0 /24 is available. Figure 3-11 shows the routing table for the same
network if the primary interface to 192.168.7.0 /24 is not available.
