Practical Exercise Solution

To complete this exercise you need to configure two dialer profiles on R3one for each caller. Use the map class with the dialer string on R3 for R1. You also have to configure a dialer profile on R1 for its communication with the central site. R2 needs to be configured for legacy DDR.

The addressing scheme is shown in Figure 7-4. Use the EIGRP protocol when configuring R3. After you are finished with your configuration, you can verify it against Examples 7-8, 7-9, and 7-10.

Example 7-8 shows the configuration of R3.
