Why do we need to assign ip address to the D channel (signaling ) when we configure ISDN-PRI in the example below :



Step 1:Specify the D channel of the first Primary Rate Interface (PRI):

AS01(config)# interface Serial 0:23


Step 2: Assign an IP address and subnet mask to the interface:

AS01(config-if)# ip address

You can assing one there, and / or on dialer interfaces. It depends on what you are doing.

These will be the address used by PPP when it runs on the B-channels.
