When placing calls, the physical interfaces in a dialer circular group use the IP address of the associated
dialer interface instead of its own. An ISDN BRI or PRI interface itself can be regarded as a dialer circular
group for its B channels. At the same time, it can be assigned to other dialer circular groups.
To configure multiple interfaces to place calls to one or more remote ends:

Command Remarks
1. Enter system view.
system-view N/A
2. Create a dialer interface and
enter its view.
interface dialer number N/A
3. Enable C-DDR.
dialercircular enable By default, C-DDR is disabled.
4. Configure the dial strings and
destination addresses for
calling remote ends.
dialer route protocol
next-hop-address [ mask
network-mask-length ]
[ vpn-instance vpn-instance-name ]
[ dial-number [ autodial | interface
interface-type interface-number ]
* ] [ broadcast | user hostname ] *
By default, no dial strings and
destination addresses are
configured.
To place a call to a single remote
end, you can use the dialer number
or dialer route command to
configure the dial string. To place
calls to multiple remote ends, you
must use the dialer route command
multiple times to configure dial
strings and destination addresses.
5. Exit to system view.
quit N/A
6. Enter physical interface view.
interface interface-type
interface-number
N/A
7. Assign the physical interface
to the dialer circular group
corresponding to the dialer
interface.
dialer circular-group number
By default, a physical interface
does not belong to any dialer
circular group.
Make sure the number arguments
in the interface dialer and dialer
circular group commands use the
same value.
8. (Optional.) Assign a priority
to the physical interface in the
dialer circular group.
dialer priority priority The default priority is 1.
Configuring multiple interfaces to receive calls from one or
more remote ends
In Figure 39, multiple interfaces at the local end receive calls from one or multiple remote ends (the
components in gray represent the routers irrelevant to the networking).
