Figure 39 Multiple interfaces receive calls from one or multiple remote ends
In this scenario, interfaces if0, if1, and if2 at the local end receive DDR calls from one or more remote
interfaces (if1, if2, if3, and if4). Because multiple interfaces are involved at the local end, configure DDR
parameters for them by configuring a dialer circular group. In addition, you can configure PAP or CHAP
authentication if PPP encapsulation is enabled on the dialer interface.
To configure multiple interfaces to receive 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.
dialer circular enable By default, C-DDR is disabled.
4. (Optional.) Configure the
interface to receive calls from
one or more remote ends.
dialer route protocol
next-hop-address [ mask
network-mask-length ]
[ vpn-instance vpn-instance-name ]
[ broadcast | user hostname ] *
If the dialer route ip
next-hop-address user hostname
command is configured at a called
party, the called party will use the
specified next hop address and
hostname to authenticate the
calling party.
Repeat this step if multiple remote
ends are involved.
5. Exit to system view.
quit N/A
6. Enter physical interface view.

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.
