- A
1. Enable IPv6 routing globally with 'ipv6 unicast-routing'
This is the first step because IPv6 routing must be enabled globally before any OSPFv3 configuration can take effect.
- B
2. Configure the OSPFv3 process with 'ipv6 router ospf <process-id>' and set the router ID
This is incorrect because the OSPFv3 process is configured after enabling IPv6 routing, but before enabling OSPFv3 on an interface.
- C
3. Enable OSPFv3 on the interface with 'ipv6 ospf <process-id> area <area-id>'
This is incorrect because enabling OSPFv3 on an interface comes after the OSPFv3 process is configured, not before.
- D
4. Verify OSPFv3 adjacency and routes with 'show ipv6 ospf neighbor' and 'show ipv6 route ospf'
This is incorrect because verification is the final step, not the first.
Quick Answer
The correct order begins with enabling IPv6 routing globally using the 'ipv6 unicast-routing' command, then configuring the OSPFv3 process with 'ipv6 router ospf <process-id>' and setting the router ID, followed by enabling OSPFv3 on the interface with 'ipv6 ospf <process-id> area <area-id>', and finally verifying the adjacency and routes using 'show ipv6 ospf neighbor' and 'show ipv6 route ospf'. This sequence is correct because IPv6 routing must be active before the OSPFv3 process can function, and the OSPFv3 process must exist before it can be applied to an interface. On the CCNA 200-301 v2 exam, this drag-and-drop task tests your understanding that OSPFv3 requires a manually configured router ID (unlike OSPFv2, which can use an IPv4 address) and that the interface-level command is the final configuration step. A common trap is forgetting to set the router ID, which prevents adjacency formation. Remember the mnemonic "E-P-A-V" (Enable, Process, Apply, Verify) to lock in the logical workflow.
CCNA IP Routing Practice Question
This 200-301 practice question tests your understanding of ip routing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Drag and drop the following steps into the correct order to configure OSPFv3 for IPv6 on a Cisco IOS-XE router, including enabling IPv6 routing, setting up the OSPFv3 process, enabling it on an interface, and verifying the adjacency and routes.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
1. Enable IPv6 routing globally with 'ipv6 unicast-routing'
This order follows the logical workflow: first enable IPv6 globally, then configure the OSPFv3 process, apply it to the interface, and finally verify the results.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Why this is correct
This is incorrect because verification is the final step, not the first.
Related concept
OSPF neighbours must agree on key parameters.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 200-301 OSPF questions on adjacency and route selection.
