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 vrf RED neighbors
EIGRP-IPv4 Neighbors for AS(100) VRF RED H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 192.168.1.2 Gi0/2 13 00:15:30 12 200 0 45 1 192.168.2.2 Gi0/3 12 00:14:20 15 200 0 32
Based on this output, what is the problem?
⚠ Common exam trap
300-410 often tests the misconception that low EIGRP sequence numbers or a Hold time below the default 15 seconds indicate a problem — candidates misread normal RTP counters as faults.
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 EIGRP adjacency is functioning correctly.
The output shows two EIGRP neighbors in VRF RED with valid Hold times (13 and 12 seconds, well above zero), non-zero Uptime (00:15:30 and 00:14:20), and Q Cnt of 0, meaning no queued packets. The Seq Num values (45 and 32) are simply the last sequence numbers received from each neighbor and are not an indicator of a problem. All fields are consistent with a healthy, stable EIGRP adjacency.
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 EIGRP neighbors are not exchanging routes because the Seq numbers are low.
Why it's wrong here
Sequence numbers of 45 and 32 simply reflect the last received EIGRP packet sequence and are unrelated to route exchange; neighbours with Q Cnt 0 are healthy. It is tempting because low sequence values can look like stale or stalled adjacencies, but EIGRP does not require high sequence numbers to exchange routes.
- ✗
Both neighbors are in the Init state.
Why it's wrong here
Neither neighbour is in Init state; the H column shows 0 and 1, meaning the adjacency is established and routes are being exchanged. It is tempting because Init appears when hellos are received but bidirectional communication is not confirmed, which is a genuine EIGRP fault, but the output here shows full adjacency.
- ✓
The EIGRP adjacency is functioning correctly.
Why this is correct
Both neighbours show stable uptime, low SRTT, zero queue count and hold timers well above expiry, so EIGRP adjacencies in VRF RED are healthy. The stem's implicit fault assumption is therefore unsupported: nothing in this output indicates a problem, making the "functioning correctly" conclusion the accurate reading of the evidence.
- ✗
The hold time of 13 seconds indicates a problem.
Why it's wrong here
A 13-second hold time is normal EIGRP behaviour; it counts down from the configured hold timer and resets on each hello, so it does not indicate a fault. It is tempting because a low hold value can suggest an imminent neighbour loss, but that only applies when the timer approaches zero without refresh.
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.
