4.2.1 Packet Tracer – Troubleshoot EIGRP for IPv4 (Answers)
|Device||Interface||IP Address||Subnet Mask||Default Gateway|
In this activity, you will troubleshoot EIGRP neighbor issues. Use show commands to identify errors in the network configuration. Then, you will document the errors you discover and implement an appropriate solution. Finally, you will verify that full end-to-end connectivity is established.
1. Use testing commands to discover connectivity problems in the network and document the problem in the Documentation Table.
2. Use verification commands to discover the source of the problem and devise an appropriate solution to implement. Document the proposed solution in the Documentation Table.
3. Implement each solution one at a time and verify if the problem is resolved. Indicate the resolution status in the Documentation Table.
4. If the problem is not resolved, it may be necessary to first remove the implemented solution before returning to Step 2.
5. After all identified problems are resolved, test for full end-to-end connectivity.
|Device||Identified Problem||Proposed Solution||Resolved?|
|R1||Has not established any adjacencies||Remove EIGRP 11 and configure EIGRP 1, advertise the directly connected networks and passive-interface g0/0 and disable automatic summarization.|
|R2||Is not forming an adjacency with R3.||Advertise the 172.31.40.228/30 network|
|R3||Is performing automatic summarization||Disable automatic summarization using the no auto-summary EIGRP subcommand|
