Versatile Routing Platform

DDR Configuration

In a Dialer Rotary Group, when the traffic bandwidth of a physical interface exceeds the preset threshold, DDR will start another physical interface and transfer data to the same destination.

Perform the following task in the dialer interface configuration mode.

Table DC-1-19Set load threshold

Operation

Command

 

 

Set load threshold

dialer load-threshold load [ either inbound outbound ]

Configure the interface encapsulated with PPP to

ppp multilink

operate in MP mode

 

9)Set autodial interval

The following command, used in combination with the key word autodial in dialer map command, is used to set the interval for DDR to make autodial attempts.

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

Table DC-1-20Set autodial interval

Operation

Command

 

 

Set autodial interval

dialer autodial-interval seconds

The default interval is 300 seconds.

1.4.2Configuring Dialer Profile

I.Introduction to Dialer Profile

Dialer Profile allows the configuration of a physical interface and the logic configuration of a call to be made separately, and then dynamically bind the two to place a call.

Dialer Profile uses Dialer Profiles to describe its dial attributes. All calls to the same destination network use the same Dialer Profiles. A Dialer Profiles include the following elements:

z A logic dial interface, corresponding to a dial string, used to reach a destination network.

z Features of the dial interface, such as idle-timeout.

z A Dialer Pool, the set of bound physical interfaces with priorities, used for dial.

In a Dialer Profiles, the relation between dial interfaces, Dialer Pool and physical interfaces is:

z One dial interface can use only one Dialer Pool.

z One Dialer Pool may contain several physical interfaces with different priorities, and a physical interface may belong to several different Dialer Pool.

Therefore, in configuring DDR with Dialer Profile, the configuration tasks for a physical interface include: select encapsulation, configure Dialer Pool to which the interface belongs, and set dial authentication mode.

The relation between dial interfaces, Dialer Pool and physical interfaces is shown in the following diagram.
