Navigating Your Hands-On Lab

In this lab, you will construct and become familiar with the VoIP lab topology to be used in subsequent labs. The lab topology contains a total of three Cisco routers. However, some of the labs can be adapted to only two routers.

Following is a list of required lab equipment:

  • Three Cisco routers running Cisco IOS Software Release 12.3(1) or later. (The IOS should support the H.323 Gateway and AutoQoS features.)

    - Router R1 should contain one serial interface and one FXS port.

    - Router R2 should contain two serial interfaces.

    - Router R3 should contain one serial interface and one FXS port.

Note

To identify an appropriate IOS image for your routers, visit Cisco's Feature Navigator, at www.cisco.com/go/fn, where you can specify the features you require for your specific router platform.


  • Two DTE-to-DCE serial cables (with the appropriate serial connectors for your routers).

  • Two analog telephones.

Figure 2-50 illustrates the lab's physical topology and IP addressing.

Task 1: Physical Connectivity

In this task, you will interconnect the lab routers.

Complete these steps:

1.
Adapting the topology shown in Figure 2-50 to your own router interfaces, interconnect routers R1 and R2 using a DTE-to-DCE serial cable. The DTE end of the cable should be connected to router R1, and the DCE end of the cable should be connected to router R2.

2.
Interconnect routers R2 and R3 using a DTE-to-DCE serial cable. The DTE end of the cable should be connected to router R2, and the DCE end of the cable should be connected to router R3.
