300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ip eigrp neighbors detail
EIGRP-IPv4 Neighbors for AS(100) H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 10.1.1.2 Gi0/0 13 00:12:34 12 200 0 45 Version 12.0/2.0, Retrans: 0, Retries: 0, Restarts: 0 Topology ids from peer: 0 Passive interface: No Hello interval: 5 Hold time: 15
Based on this output, what is the problem?
⚠ Common exam trap
Cisco often tests the misconception that a hold time of 15 seconds is too short, but in EIGRP this is the default for high-speed interfaces and is perfectly normal; candidates may confuse it with OSPF's shorter dead intervals or misinterpret the 'Passive interface' field if they do not read the 'No' value.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The neighbor is operating normally with no issues.
The output shows a fully established EIGRP neighbor adjacency with no errors. The 'Passive interface: No' confirms the interface is not configured as passive, the retransmission count is 0, and the hold time of 15 seconds is the default for a 5-second hello interval on high-speed interfaces. All metrics (SRTT, RTO, Q count, Seq Num) indicate stable operation, so there is no problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The neighbor is operating normally with no issues.
Why this is correct
All parameters are within normal range, and the neighbor is fully established.
- ✗
The interface is configured as passive, preventing neighbor formation.
Why it's wrong here
The output says 'Passive interface: No', meaning it is not passive.
- ✗
The neighbor has a high number of retransmissions.
Why it's wrong here
Retransmissions are 0, indicating no issues.
- ✗
The hold time of 15 seconds is too short and may cause flapping.
Why it's wrong here
The hold time of 15 seconds is the default for EIGRP on LAN interfaces and is acceptable.
Quick reference
Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
