Step 1: Connect the equipment
- Connect Router1 to Router2 and Router3 using serial cables.
- Connect Router2 to Router3 using serial cables.
- Connect a PC with a console cable to perform configurations on the routers.
Step 2: Perform basic configurations on the routers
- Establish a console session with Router1 and configure hostname, passwords, and interfaces as described in the table. Save the configuration.
- Establish a console session with Router2 and perform a similar configuration, using the addresses and other information from the table. Save the configuration.
- Establish a console session with Router3. Configure hostname, passwords, and interfaces according to the table. Save the configuration.
Step 3: Configure EIGRP routing with default commands
- On Gateway, configure EIGRP as the routing protocol with an autonomous system number of 100, and advertise the appropriate networks.
- On Branch1, configure EIGRP as the routing protocol with an autonomous system number of 100, and advertise the appropriate networks:
- Perform a similar configuration on Branch2, using EIGRP 100 and advertising the appropriate networks.
Step 4: Verify the routing configuration
- View the routing table on Gateway.
- Which subnets are not reported in this output? Jawaban: The subnets configured for the 172.16.0.0 and 172.17.0.0 networks are absent.
- Why are there two paths reported for the 10.0.0.8/30 route? Jawaban: Because no bandwidth commands have been configured, EIGRP has two equal-cost paths to report.
Step 5: Remove Automatic summarization
On each of the three routers, remove automatic summarization to force EIGRP to report all subnets. A sample command is given for Gateway.
Step 6: Verify the routing configuration
View the routing table again on Gateway.
Step 7: Configure manual summarization
On Branch2, configure manual summarization to force EIGRP to summarize only the 172.17.0.0 subnets.
Step 8: Reflection
- Although removing automatic summarization solved the issue of missing subnets, what possible problem could it cause? Jawaban : The routing table is very long, and that will slow down the lookup process.
- How could removing automatic summarization help in troubleshooting an EIGRP network? Jawaban : Checking the output against all possible subnets will reveal which subnet(s) are missing. Those are the connections and configurations that need to be checked.
