Creating the CDMA Ix Interface
To create the CDMA Ix interface, use the following commands in global configuration mode:
Creating a Loopback Interface
We recommend that you create a loopback interface and then associate the loopback interface IP address
to the virtual template, rather than directly configuring an IP address on the virtual template.
To create a loopback interface, use the following commands in global configuration mode:
Creating a Virtual Template Interface and Associating It With the PDSN Application
Creating a virtual template interface allows you to establish an interface configuration and apply it
dynamically.
To create a virtual template interface that can be configured and applied dynamically, use the following
commands in global configuration mode:
Command Purpose
Router(config)# interface cdma-Ix1
Defines the CDMA virtual interface for the R-P
interface.
Router(config-if)# ip address ip-address mask
Assigns an IP address and mask to the CDMA-Ix
virtual interface. This IP address will be used by
the RAN to communicate with the PDSN.
Command Purpose
Router(config)# interface loopback number
Creates a loopback interface. A loopback interface
is a virtual interface that is always up.
Router(config-if)# ip address ip-address mask
Assigns an IP address to the loopback interface.
Command Purpose
Router(config) interface virtual-template number
Creates a virtual template interface.
Router(config-if)# ip unnumbered loopback number
Assigns the previously defined loopback IP
address to the virtual template interface.
Router(config-if)# ppp authentication chap pap optional
Enables PPP authentication.
Router(config-if)# ppp accounting none
Disables PPP accounting to enable 3GPP2
accounting.
Router(config-if)# ppp accm 0
Specifies the transmit ACCM table value. The
value must be specified as 0.
Router(config-if)# ppp timeout idle value
Specifies the PPP idle timeout.
Router(config-if)# exit
Exit interface configuration mode.
Router(config)# cdma pdsn virtual-template
virtual-template-num
Associates a virtual template with the PDSN
application.
