Review of basic router configuration commands

1. Why is the no shutdown command unnecessary for Lo0?

2. If the IP address on Lo0 was in the 192.168.100.0 network, what additional command would be required?3. What is the purpose of the logging synchronous command?

4. What is significant about the number 84 in the OSPF command?

5. Verify that the Serial interfaces are up and OSPF is FULL (sh ip ospf neighbor).

6. From HQ1 ping the serial 0/0 interface of RemoteEnd2. Re-check configuration and do not continue until successful.

7. Pick up the receivers on the analog phones and listen for dial-tone. What do you hear?

Save the configuration now in the location specified by your instructor and name it BasicStartingConfig. Then begin to enter the follow commands in the respective routers.

HQ1

RemoteEnd2dial-peer voice 1 pots

dial-peer voice 1 voip

destination-pattern 1111


port 1/0/0

session target ipv4:10.10.11.1

dial-peer voice 2 pots

dial-peer voice 2 pots



port 1/0/1

port 1/0/0







Name:1. Again pick up the phone receiver and listen. What is you hear?

2. What does the term pots mean?

3. Ensure that all phones can place (dial) and receive (ring) calls.4. From destination-pattern 2222 call destination-pattern 1111. Conduct an evaluation the connection quality. How much delay is in the circuit? How much echo? Is there any audio drop-outs? How much background noise is present? Do not hang-up the phone (leave off-hook), continue to monitor and record your observations.

5. On the serial interface of HQ1 change the clockrate to 32000. Is there any discernable difference in connection quality?

6. Now lower the clockrate to 28800. What is the difference?

7. Return the clockrate to 1300000 and enter the show voice port command.

8. What type of voice port is 1/0/0?Enter the show dial-peer voice command. Note the first line.

1. What destination pattern is associated with voice port 1/0/1?

2. Enter the show dial-peer voice 3 command. How does the first line of the output differ from earlier?

3. Destination-pattern 2222 is associated with what target session?

4. What compression algorithm (codec) is being utilized?Verify the configuration is completely accurate and save it as BasicVoIPconfig.
