A network engineer runs the following command to troubleshoot an EIGRP issue:
R1# show ip eigrp topology 10.1.1.0/24 detail
IP-EIGRP (AS 100): Topology entry for 10.1.1.0/24 State: Passive, Query origin flag: 1, 1 Successor(s), FD is 131072 Routing Descriptor Blocks:
10.1.2.2 (GigabitEthernet0/0), from 10.1.2.2, Send flag: 0x0
Composite metric: (131072/130816), Route is Internal Vector metric: Minimum bandwidth is 10000 Kbit Total delay is 100 microseconds Reliability is 255/255 Load is 1/255 Minimum MTU is 1500 Hop count is 1 Originating router: 10.1.2.2 External data: Not advertised Protocol: EIGRP Route tag: 0 Extended community: None
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 route is learned from a single neighbor and is in a stable state.
The output shows detailed information about the EIGRP topology entry for 10.1.1.0/24. The route is internal, with a single successor via 10.1.2.2. The FD is 131072, and the RD is 130816. The route is in Passive state.
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 route is an external EIGRP route redistributed from another protocol.
Why it's wrong here
The output states 'Route is Internal', so it is not external.
- ✓
The route is learned from a single neighbor and is in a stable state.
Why this is correct
The route has one successor and is Passive, indicating stability.
- ✗
The route has multiple successors and is load-balanced.
Why it's wrong here
Only one successor is listed.
- ✗
The route is in Active state, meaning a query is in progress.
Why it's wrong here
The state is Passive.

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.
