EIGRP Troubleshooting →hardMultiple SelectObjective-mapped

Quick Answer

The answer is **show ip protocols**, as this command is the primary tool for verifying that the redistribute command is correctly configured under the EIGRP process, including the proper metric and route-map settings. When troubleshooting EIGRP route redistribution, you must first confirm that the source protocol’s routes exist in the routing table and that the redistribution statement is active; show ip protocols displays exactly which protocols are being redistributed into EIGRP, the assigned metrics, and any filtering rules. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to isolate redistribution failures—a common trap is to jump to show ip eigrp topology, which only shows internal EIGRP routes, not redistributed ones. Remember that redistribution issues are almost always a configuration or metric mismatch, not a neighbor problem, so start with show ip protocols to see if the redistribute command is even present. A useful memory tip: “Protocols first, topology last” — always check the redistribution policy before looking at the EIGRP topology table.

300-410 EIGRP Troubleshooting Practice Question

This 300-410 practice question tests your understanding of eigrp troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Which THREE commands can be used to verify and troubleshoot EIGRP route redistribution issues, specifically when routes are not being redistributed correctly? (Choose THREE.)

Question 1hardmulti select

Study the full EIGRP explanation →

A
'show ip eigrp topology'
Why wrong: This command shows only EIGRP-learned routes in the topology table; it does not show routes redistributed into EIGRP from other protocols unless they have been successfully redistributed and are in the topology.
B
'show ip route'
This command shows the routing table, including routes from all sources. It can verify whether redistributed routes are present and have the correct administrative distance and metric.
C
'debug eigrp fsm'
This debug command shows EIGRP Finite State Machine events, including route updates and redistribution events, helping to identify if redistribution is occurring and any errors.
D
'show ip protocols'
This command displays the routing protocol configuration, including redistribution statements, route filters, and administrative distances, allowing verification of redistribution parameters.
E
'ping'
Why wrong: Ping tests end-to-end connectivity but does not provide specific information about redistribution configuration or errors.

Correct answer & explanation

✓

'show ip route'

Troubleshooting redistribution involves verifying that routes are in the source routing protocol, that the redistribute command is correct, and that metrics are set. 'show ip eigrp topology' shows EIGRP routes, not redistributed routes from other protocols. 'show ip route' shows all routes in the routing table. 'debug eigrp fsm' tracks EIGRP events. 'show ip protocols' shows redistribution configuration. 'ping' verifies reachability but not redistribution.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Trap categories for this question

Command / output trap
This command shows only EIGRP-learned routes in the topology table; it does not show routes redistributed into EIGRP from other protocols unless they have been successfully redistributed and are in the topology.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What to study next

Got this wrong? Here's your next step.

Identify which 300-410 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Which TWO commands can be used to troubleshoot EIGRP route redistribution issues when routes are not appearing in the routing table? (Choose TWO.)

medium

✓ A.show ip protocols
B.show ip route
✓ C.show ip eigrp topology all-links
D.show ip ospf database
E.debug ip routing

Why A: The 'show ip protocols' command confirms redistribution configuration and route filters. The 'show ip eigrp topology all-links' displays all known routes, including those that may be suppressed by metrics or filters. The other options are either for OSPF or do not show redistribution-specific information.
