300-410 Practice Question: Runs the following command to verify OSPF…
A network engineer runs the following command to verify OSPF interface details:
R1# show ip ospf interface gigabitethernet0/0 detail
GigabitEthernet0/0 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: 10 Transmit Delay is 1 sec, State BDR, Priority 1 Designated Router (ID) 2.2.2.2, Interface address 10.1.1.2 Backup Designated router (ID) 1.1.1.1, Interface address 10.1.1.1 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 Can be protected by per-prefix Loop-Free Fast Reroute Can be used for per-prefix Loop-Free Fast Reroute repair paths Index 1/1, flood queue length 0 Next 0(0)/0(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 (Designated Router) Suppress hello for 0 neighbor(s)
What does this output indicate?
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 router has a full adjacency with the DR (2.2.2.2).
The output shows detailed OSPF interface parameters, including state, timers, and neighbor information.
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 on this segment.
Why it's wrong here
The state is BDR (Backup Designated Router), not DR.
- ✓
The router has a full adjacency with the DR (2.2.2.2).
Why this is correct
The output shows 'Adjacent with neighbor 2.2.2.2 (Designated Router)' indicating a full adjacency.
- ✗
The interface is in a passive state with no neighbors.
Why it's wrong here
Neighbor Count is 1, so there is an active neighbor.
- ✗
The Hello timer is set to 40 seconds.
Why it's wrong here
The Hello timer is 10 seconds, Dead timer is 40 seconds.

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.
