Configuration procedure
Method 1: Use the dial string configured in the dialer route command to call back the client.
1. Configure Router A:
# Create dialer group 1 and configure a dial rule for it.
<RouterA> system-view
[RouterA] dialer-group 1 rule ip permit
# Configure an IP address for interface Serial 2/1/0.
[RouterA] interface serial 2/1/0
[RouterA-Serial2/1/0] ip address 100.1.1.1 255.255.255.0
# Configure the interface to operate as an asynchronous interface in protocol mode.
[RouterA-Serial2/1/0] physical-mode async
[RouterA-Serial2/1/0] async-mode protocol
# Enable traditional DDR on the interface.
[RouterA-Serial2/1/0] dialer circular enable
# Associate the interface with dialer group 1.
[RouterA-Serial2/1/0] dialer-group 1
# Configure the dial string for calling Router B.
[RouterA-Serial2/1/0] dialer route ip 100.1.1.2 8810052
