- A
The 'route-replicate' command is not configured under the VRF, so it does not take effect; it must be placed under 'ip vrf BLUE'.
The route-replicate command is a subcommand of the VRF configuration; if entered in global configuration mode, it is ignored or causes an error.
- B
The OSPF route in VRF BLUE has a tag that prevents it from being leaked.
Why wrong: No tag is mentioned; the route-replicate command does not filter by default.
- C
The route 10.10.10.0/24 is not in the VRF BLUE table on R1 because it is learned via R2.
Why wrong: The route is in R2's VRF table, but R1 must have it in its VRF table to leak it; the scenario does not specify if R1 has the route.
- D
The route-replicate command requires a route-map to specify the prefix, but none is provided.
Why wrong: The command can use a prefix list or route-map; the example shows a prefix, but the command syntax may be incorrect.
300-410 Device Management Practice Question
This 300-410 practice question tests your understanding of device management. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A VRF-aware network has VRF BLUE on routers R1 and R2. Routes are leaked between VRF BLUE and the global table on R1 using route-replicate. R2 shows: 'show ip route vrf BLUE' includes a route 10.10.10.0/24 learned via OSPF, but 'show ip route' (global) on R1 does not include this route. R1 configuration: ip vrf BLUE, rd 100:1, route-target export 100:1, route-target import 100:1, and 'route-replicate from vrf BLUE to global unicast 10.10.10.0 255.255.255.0'. What is the root cause?
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-replicate' command is not configured under the VRF, so it does not take effect; it must be placed under 'ip vrf BLUE'.
The 'route-replicate' command must be configured under the VRF configuration mode (i.e., 'ip vrf BLUE') to take effect. In the given scenario, it was likely applied in global configuration mode, which is incorrect. Without proper placement, the route replication does not occur, so the 10.10.10.0/24 route remains only in the VRF BLUE table on R1 and is not copied to the global routing table.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the exact placement of VRF-related commands, and the trap here is that candidates assume 'route-replicate' is a global command like 'router ospf', when in fact it must be nested under the VRF configuration.
Trap categories for this question
Command / output trap
No tag is mentioned; the route-replicate command does not filter by default.
Scenario analysis trap
The route is in R2's VRF table, but R1 must have it in its VRF table to leak it; the scenario does not specify if R1 has the route.
Detailed technical explanation
How to think about this question
The 'route-replicate' command is a VRF-specific feature that copies routes from one routing table (e.g., VRF) to another (e.g., global) within the same router. It is configured under the 'ip vrf' submode, not global config. Under the hood, route-replicate uses the RIB to install the replicated route with a special administrative distance (default 255) to avoid interfering with directly learned routes. In real-world MPLS L3VPN designs, this is often used to leak a default route or specific prefixes between VRF and global tables for inter-VRF or Internet access.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
Visual reference
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.
