A network engineer runs the following command to troubleshoot a VRF-Lite issue:
R1# show ip eigrp vrf CUSTOMER_B topology 10.1.1.0/24
Output: IP-EIGRP (AS 100): Topology entry for 10.1.1.0/24 for VRF CUSTOMER_B State is Passive, Query origin flag is 1, 1 Successor(s), FD is 131072 Routing Descriptor Blocks:
10.1.1.1 (GigabitEthernet0/1), from 10.1.1.1, Send flag is 0x0
Composite metric is (131072/128256), Route is Internal Vector metric: Minimum bandwidth is 100000 Kbit Total delay is 100 microseconds Reliability is 255/255 Load is 1/255 Minimum MTU is 1500 Hop count is 1
What does this output indicate?
⚠ Common exam trap
The trap is misreading 'Passive' as a problem — in EIGRP, Passive means stable and converged, while Active means a query is in progress; candidates who think Passive is bad pick the wrong answer.
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 10.1.1.0/24 has one successor with a feasible distance of 131072 and is learned via 10.1.1.1.
The output shows 'State is Passive' (no query in progress), '1 Successor(s)', and 'FD is 131072', with the successor learned via 10.1.1.1 on GigabitEthernet0/1. The composite metric (131072/128256) shows the feasible distance and reported distance, and 'Route is Internal' confirms it is a native EIGRP route, not redistributed. This is a healthy, stable EIGRP topology entry.
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 10.1.1.0/24 is in Active state, indicating an EIGRP query is in progress.
Why it's wrong here
The output shows "State is Passive" with the query origin flag set, meaning no query is outstanding; Active state would appear only while a route is being queried. It is tempting because Active state signals convergence trouble, and it would be correct if the route were awaiting replies.
- ✓
The route 10.1.1.0/24 has one successor with a feasible distance of 131072 and is learned via 10.1.1.1.
Why this is correct
The topology entry shows state Passive with one successor and a feasible distance of 131072, reached through 10.1.1.1 on GigabitEthernet0/1. The reported composite metric (131072/128256) confirms the successor's distance and advertised distance for that route.
- ✗
The route 10.1.1.0/24 is an external EIGRP route redistributed into the VRF.
Why it's wrong here
The line "Route is Internal" identifies this as a native EIGRP route within AS 100, not a redistributed external route, which would show "Route is External" with an originating router. It is tempting because redistribution is common in VRF-Lite designs, and it would be correct if the entry carried an external tag.
- ✗
The route 10.1.1.0/24 has multiple successors due to equal-cost paths.
Why it's wrong here
The output states one successor, so equal-cost multipath is not present; a single routing descriptor block is listed. It is tempting because EIGRP does support multiple successors, and this option would be correct if several descriptor blocks shared the same feasible distance.

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.
