HP MSR Router Series - ISDN-Based Bundle DDR Configuration Example

201
[RouterB-Bri2/4/0] dialer route ip 100.1.1.1 8810048
3. Configure Router C:
# Create dialer group 1 and configure a dial rule for it.
<RouterC> system-view
[RouterC] dialer-group 1 rule ip permit
# Configure an IP address for interface BRI 2/4/0.
[RouterC] interface bri 2/4/0
[RouterC-Bri2/4/0] ip address 100.1.1.3 255.255.255.0
# Enable traditional DDR on the interface.
[RouterC-Bri2/4/0] dialer circular enable
# Associate the interface with dialer group 1.
[RouterC-Bri2/4/0] dialer-group 1
# Configure the dial string for calling Router A.
[RouterC-Bri2/4/0] dialer route ip 100.1.1.1 8810048
Verifying the configuration
# Verify that Router A can successfully ping Router B and Router C
# Verify that Router B and Router C cannot ping each other.

Configure bundle DDR to meet the following requirements:
• Allow Router A to call Router B and Router C from multiple interfaces.
• Disable Router B and Router C from calling each other.
