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?
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 'show ip eigrp vrf topology' command displays the EIGRP topology table entry for a specific prefix within a VRF. The output shows the route 10.1.1.0/24 is in Passive state, meaning no EIGRP query is pending. It has one successor (the best path) with a feasible distance (FD) of 131072. The next hop is 10.1.1.1 via GigabitEthernet0/1.
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
Incorrect. The state is Passive, not Active.
- ✓
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
Correct. The output shows one successor, FD 131072, and next hop 10.1.1.1.
- ✗
The route 10.1.1.0/24 is an external EIGRP route redistributed into the VRF.
Why it's wrong here
Incorrect. The output says 'Route is Internal', not external.
- ✗
The route 10.1.1.0/24 has multiple successors due to equal-cost paths.
Why it's wrong here
Incorrect. There is only one successor listed in the Routing Descriptor Blocks.

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.
