Network requirements

As shown in Figure 41, three routers are located on a network segment: Router A with the IP address of

100.1.1.1/24, Router B with the IP address of 100.1.1.2/24, and Router C with the IP address of

100.1.1.3/24.

Configure C-DDR to allow Router A to call Router B and Router C from multiple interfaces, but disable

Router B and Router C from calling each other.
