In this scenario, interface if0 at the local end receives DDR calls from one or more remote interfaces (if1,
if2, and if3). Since calls are received by a single interface, you can configure C-DDR by configuring a
dialer circular group, or you can configure C-DDR directly on the physical interface. In addition, you can
configure PAP or CHAP authentication if PPP encapsulation is enabled on the dialup interface.
To configure an interface to receive calls from one or more remote ends directly on a physical interface:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter physical interface view.
interface interface-type
interface-number
N/A
3. Enable C-DDR on the
interface.
dialer circular enable
By default, C-DDR is disabled on a
physical interface.
4. (Optional.) Configure the
interface to receive calls from
one or more remote ends.
dialer route protocol
next-hop-address [ mask

[ vpn-instance vpn-instance-name ]
[ broadcast | user hostname ] *
To receive calls from multiple
remote ends, configure this
command multiple times.
If the dialer route ip
next-hop-address user hostname
command is configured at the
called party, the called party will
use the specified next hop address
and hostname to authenticate the
calling party.
