Versatile Routing Platform

DDR Configuration

To configure a Dialer Rotary Group, follow the steps below:

Step 1: create a logic dial interface.

Please use the following command in global configuration mode.

Table DC-1-4Create a logic dial interface

Operation

Command

 

 

Create a logic dial interface

interface dialer number

In the command, number is both the interface number of the logic dial interface and the identification number of Dialer Rotary Group. That is to say, when a logic dial interface is created, a Dialer Rotary Group is also specified for this interface.

Step 2: enable DDR.

Please use this command in the configuration mode of the logic dial interface.

For the command format, please refer to Step 1 of “Call to a single point”.

Step 3: designate multiple destinations for this Dialer Rotary Group.

Please use this command in the configuration mode of the dial interface.

Table DC-1-5Set different dial strings for different destinations

Operation

Command

 

 

Set different dial strings for different

dialer map protocol next-hop-address Dialstring [:

destinations

isdnsubaddress]

Step 4: put the physical interface into Dialer Rotary Group.

Table DC-1-6Put the designated physical interface into Dialer Rotary Group.

Operation

Command

 

 

Enter the configuration mode of the designated physical interface

interface interface-type interface-number

(used in global configuration mode)

 

Put the physical interface into Dialer Rotary Group (used in the

dialer rotary-group number

configuration mode of the designated physical interface)

 

The physical interface in Dialer Rotary Group doesn’t use its own IP address—in application, it will inherit the IP address of the logic dial interface. The parameter number in the command dialer rotary-group number in the configuration mode of the physical interface should be the same as the number in the command interface dialer number in the configuration mode of the logic interface corresponding to the physical interface.

In addition, an ISDN interface (BRI or PRI) itself can be regarded as Dialer Rotary Group of its subordinate B channel. Meanwhile, it can serve as a physical interface in other Dialer Rotary Groups.

Following is the schematic diagram of Dialer Rotary Group.
