Serial Interface D Channel Configuration

[DanielBowen]

I have configured an E1 PRI controller for ISDN30, and need to configure the serial0/1:15 interface (D channel). I want to assign an IP address but do not know where to get the IP address from (LAN network number, made up address etc)

Any help would be great !

Thanks,

Daniel

NFAS Primary and Backup D Channels Example
The following example configures ISDN PRI and NFAS on three T1 controllers of a Cisco 7500 series router. The NFAS primary D channel is configured on the 1/0 controller, and the NFAS backup D channel is configured on the 1/1 controller. No NFAS D channel is configured on the 2/0 controller; it is configured for 24 B channels.

Once the NFAS primary D channel is configured, it is the only interface you see and have to configure; DDR configuration for the primary D channel--which is distributed to all B channels--is also included in this example.
