A network engineer runs the following command to troubleshoot an Administrative Distance issue:
R1# show ip ospf interface detail GigabitEthernet0/0
GigabitEthernet0/0 is up, line protocol is up Internet Address 10.1.1.1/24, Area 0, Attached via Network Statement Process ID 1, Router ID 1.1.1.1, Network Type BROADCAST, Cost: 1 Topology-MTID Cost Disabled Shutdown Topology Name 0 1 no no Base 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 Can be protected by per-prefix Loop-Free Fast Reroute Can be used for per-prefix Loop-Free Fast Reroute remote-LFA tunnels Index 1/1/1, flood queue length 0 Next 0x0(0)/0x0(0)/0x0(0) Last flood scan length is 1, maximum is 1 Last flood scan time is 0 msec, maximum is 0 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)
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 interface is an OSPF broadcast interface with a cost of 1, and the router is the Designated Router.
The output shows detailed OSPF interface information, including the cost, timers, and neighbor state. It does not directly show administrative distance, but it is relevant for understanding OSPF operation.
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 interface is an OSPF broadcast interface with a cost of 1, and the router is the Designated Router.
Why this is correct
The output clearly states State DR, indicating this router is the Designated Router on this segment.
- ✗
The interface has an administrative distance of 110.
Why it's wrong here
Administrative distance is not shown in this output; it is a per-protocol value.
- ✗
The neighbor 2.2.2.2 is not fully adjacent because it is a backup designated router.
Why it's wrong here
The neighbor is listed as Adjacent, meaning full adjacency.
- ✗
The OSPF process ID is 100.
Why it's wrong here
The process ID is 1, not 100.

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.
