2. Create a dialer group and
configure a dial rule.

{ protocol-name { deny | permit } |
acl { acl-number | name

By default, no dialer group exists.

4. Associate the dialer group with
the dialup interface.
dialer-group group-number
By default, a dialup interface is not
associated with any dialer group.
A dialup interface can be
associated with only one dialer
group.
Configuring traditional DDR
For traditional DDR, you can configure PAP or CHAP authentication (see "Configuring PPP and MP"). HP
recommends that you configure PAP or CHAP authentication for security purposes.
When you configure PAP or CHAP authentication, follow these guidelines:
• Configure PAP or CHAP authentication on a physical interface if you configure DDR parameters
directly on the physical interface.
• Configure PAP or CHAP authentication on the dialer interface if you configure DDR parameters
through a dialer circular group.
Configuring an interface to place calls
To configure an interface to place calls, enable DDR and configure dial strings.
When you configure an interface to place calls, follow these guidelines:
• To configure an interface to place calls to a single site, use the dialer number or dialer route
command to specify the dial string used to reach the site. To configure an interface to place calls to
multiple sites, use the dialer route command multiple times to specify the dial strings to reach the
sites.
• You can configure multiple dial strings for a single destination for dial backup by using the dialer
route command. If a dial string fails to reach the destination, another dial string will be used.
• To configure one interface to place calls, you can perform the configuration on the physical
interface or through a dialer circular group. To configure multiple interfaces to place calls, you can
perform the configuration only through a dialer circular group.
To configure an interface to place calls directly on a physical interface:
