ISDN-based traditional DDR configuration example

Network requirements
As shown in
network segment.
Configure traditional 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.
Figure 57, the interfaces BRI 2/4/0 of Router A, Router B, and Router C are in the same
