C 10.1.8.128 is directly connected, Loopback2
R 10.1.1.128 [120/1] via 172.16.1.1, 00:00:21, Serial0/1
R 10.1.0.128 [120/1] via 172.16.1.1, 00:00:21, Serial0/1
R* 0.0.0.0/0 [120/1] via 172.16.1.1, 00:00:21, Serial0/1
Step 2. Troubleshoot, if necessary, to obtain output similar to the preceding output.
Step 3. Once finished, capture your scripts for your records and erase/reload the routers.
Task 6: Challenge
Looking forward to your studies of EIGRP, you will learn that it is possible to reduce the size of the routing
tables on RTA and RTB by configuring EIGRP to summarize the simulated LANs into one route.
What summary route would you configure on RTB to send to RTA? Record the summary route with the
correct prefix length here:
10.1.8.0/21
What summary route would you configure on RTA to send to RTB? Record the summary route with the
correct prefix length here:
10.1.0.0/21
What interface would send the summary on RTB?
Serial 0/1
What interface would send the summary on RTA?
Serial 0/0
Now use the Cisco IOS help facility to discover a command you can use to configure a summary route. To
get you started on RTA, enter interface configuration mode for the interface attached to RTB. Then enter
ip ?. Can you find an ip command that looks like a summary route? Continue to use the help facility to
discover all the parameters and configure your summary route.
You may want to help the students through this process of discovering additional features of the IOS by
using the help facility. The following output shows how this discovery process might occur:
RTA(config)#interface s0/0
RTA(config-if)#ip ?
Interface IP configuration subcommands:
access-group Specify access control for packets

bgp BGP interface commands
broadcast-address Set the broadcast address of an interface
cef Cisco Express Fowarding interface commands
cgmp Enable/disable CGMP
directed-broadcast Enable forwarding of directed broadcasts
dvmrp DVMRP interface commands
hello-interval Configures IP-EIGRP hello interval
