Packet Tracer Companion: Troubleshooting a VLSM
Addressing Design (6.4.3)
You can now open the file LSG02-Lab643.pka on the CD-ROM that accompanies this topic to repeat
this activity using Packet Tracer. Remember, however, that Packet Tracer is not a substitute for a
hands-on lab experience with real equipment. A summary of the instructions is provided within the
activity.

Activity 6-4: Basic Route Summarization (6.4.4)
Upon completion of this activity, you will be able to determine summarized routes that can be used to
reduce the size of routing tables.
Scenario
In this activity, you have been given the network shown in Figure 6-19. The subnetting and address
assignments have already been completed for the network segments, as shown in Table 6-12.
Determine summarized routes that can be used to reduce the number of entries in the routing tables.
