Pstn-Based Bundle Ddr Configuration Example - HPE FlexNetwork MSR series Configuration Manual

# Create dialer group 1 and configure a dial rule for it.
<RouterC> system-view
[RouterC] dialer-group 1 rule ip permit
# Configure Serial 2/1/0 to operate as an asynchronous interface in protocol mode.
[RouterC] interface serial 2/1/0
[RouterC-Serial2/1/0] physical-mode async
[RouterC-Serial2/1/0] async-mode protocol
# Configure an IP address for the interface.
[RouterC-Serial2/1/0] ip address 100.1.1.3 255.255.255.0
# Enable traditional DDR on the interface.
[RouterC-Serial2/1/0] dialer circular enable
# Associate dialer group 1 with the interface.
[RouterC-Serial2/1/0] dialer-group 1
# Configure two dial strings for calling Router A.
[RouterC-Serial2/1/0] dialer route ip 100.1.1.1 8810048
[RouterC-Serial2/1/0] dialer route ip 100.1.1.1 8810049
[RouterC-Serial2/1/0] quit
# Configure the user line to be used, and enable modem dial-in and dial-out on it.
[RouterC] line tty1
[RouterC-line-tty1] modem enable both
Verifying the configuration
# Verify that Router A can successfully ping Router B and Router C. (Details not shown.)
# Verify that Router B and Router C cannot ping each other. (Details not shown.)

PSTN-based bundle DDR configuration example

Network requirements
As shown in
•
Dialer0 interfaces of Router A and Router B are in the same network segment.
•
Dialer1 interface of Router A and the Dialer0 interface of Router C are in the same network
segment.
Configure bundle DDR to meet the following requirements:
•
Router A can call Router B and Router C from multiple interfaces.
•
Router B and Router C cannot each other.
