You can now open the file LSG02-Lab841.pka on the CD-ROM that accompanies this topic to repeat
this portion of the hands-on lab 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 provid-
ed within the activity.

Task 1: Make Changes Between Scenario A and Scenario B
Remove the RIP configuration from R3 and configure a static route to 172.16.0.0/16.
Step 1.
R3(config)#
no router rip
R3(config)#
ip route 172.16.0.0 255.255.0.0 Serial0/0/1
Remove the 192.168.1.0 network from the R2 RIP configuration.
Step 2.
R2(config)#
router rip
R2(config-router)#
no network 192.168.1.0
Add a static default route to R3 on the R2 router.
Step 3.
Include the
default-information originate
command in the configuration so that the
default static route is included in the RIP updates.
R2(config)#
ip route 0.0.0.0 0.0.0.0 Serial0/0/1
R2(config)#
router rip
R2(config-router)#
