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 ospf interface GigabitEthernet0/1
GigabitEthernet0/1 is up, line protocol is up Internet Address 10.1.1.1/24, Area 0 Process ID 1, Router ID 1.1.1.1, Network Type BROADCAST, Cost: 1 Transmit Delay is 1 sec, State DR, Priority 1 Designated Router (ID) 1.1.1.1, Interface address 10.1.1.1 Backup Designated router (ID) 2.2.2.2, Interface address 10.1.1.2 Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5 oob-resync timeout 40 Hello due in 00:00:03 Supports Link-local Signaling (LLS) Cisco NSF helper support enabled IETF NSF helper support enabled Index 1/1, flood queue length 0 Next 0x0(0)/0x0(0) Last flood scan length is 1, maximum is 25 Last flood scan time is 0 msec, maximum is 4 msec
Neighbor Count is 1, Adjacent neighbor count is 1
Adjacent with neighbor 2.2.2.2 (Backup Designated Router) Suppress hello for 0 neighbor(s)
Based on this output, what is the problem?
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 output shows no external routes are being redistributed, but this is a normal interface status.
The output shows R1 is the Designated Router (DR) on a broadcast network. The neighbor count is 1, which is normal. However, the problem might be that redistribution is not happening because the interface is in area 0, but no external routes are seen. The output itself does not show a direct problem; it is a normal OSPF interface state. The question likely expects the candidate to note that the interface is functioning correctly, but the context of redistribution might imply that redistribution is configured but not working due to other issues.
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 router is the DR, which is normal, but the neighbor count of 1 indicates only one OSPF neighbor is present.
Why it's wrong here
This is a normal state; no problem is indicated.
- ✗
The interface is in area 0, but redistribution of external routes requires a route-map to set the metric.
Why it's wrong here
Redistribution does not require a route-map; it can be done with default metrics.
- ✓
The output shows no external routes are being redistributed, but this is a normal interface status.
Why this is correct
The interface output is normal; redistribution status is not shown here. The candidate must understand that this command does not show redistribution information.
- ✗
The router ID is 1.1.1.1, which is not reachable from other routers.
Why it's wrong here
The router ID is an IP address used for OSPF, but reachability is not an issue here.
Visual reference
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.
