Quick Answer
The correct answer includes the statement that OSPFv3 uses the same basic algorithm as OSPFv2 but is designed for IPv6, alongside two other valid statements about static routes and link-local next-hops. This is accurate because OSPFv3 retains the core SPF (Shortest Path First) algorithm and link-state database structure from OSPFv2, but it operates per-link rather than per-subnet and uses IPv6-specific LSA types. On the CCNA 200-301 v2 exam, IPv6 routing concepts often test your ability to distinguish between the configuration syntax for static routes—where the `ipv6 route` command mirrors `ip route` in IPv4—and the critical detail that a directly attached static route can use a link-local address as the next hop, a common trap for those who assume only global unicast addresses work. A frequent memory tip is to remember that OSPFv3 runs on a link, not a subnet, so think “link-local next-hop for OSPFv3 neighbors” to avoid confusing it with OSPFv2’s subnet-based design.
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.

Correct answer & explanation
✓
IPv6 static routes can be configured using the 'ipv6 route' command.
All three statements are correct. The 'ipv6 route' command is used to configure static routes in IPv6, similar to 'ip route' in IPv4. A directly attached IPv6 static route can indeed use a link-local address as the next hop, which is common for point-to-point interfaces. OSPFv3 (OSPF for IPv6) uses the same fundamental SPF algorithm and link-state concepts as OSPFv2 but is designed to support IPv6 addressing and runs per-link rather than per-subnet.
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 nuance that a link-local address can be used as a next hop for a directly attached IPv6 static route only if the exit interface is explicitly specified, leading candidates to incorrectly think link-local addresses are never valid next hops.
Detailed technical explanation
How to think about this question
When configuring an IPv6 static route with a link-local next-hop address, you must also specify the exit interface (e.g., 'ipv6 route 2001:db8::/32 GigabitEthernet0/0 FE80::1') because link-local addresses are not globally routable and require the interface context. OSPFv3 uses the same LSA types as OSPFv2 but with different payloads; for example, Type 1 LSAs carry IPv6 prefixes via prefix options, and OSPFv3 runs on a per-link basis, meaning multiple IPv6 subnets can exist on the same link without needing separate OSPF instances.
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.

Same concept, more angles

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. What is the main purpose of this configuration? ipv6 route 2001:db8:100::/64 GigabitEthernet0/0
hard- ✓ A.It creates a specific IPv6 static route to 2001:db8:100::/64 out GigabitEthernet0/0.
- B.It enables OSPFv3 on GigabitEthernet0/0.
- C.It creates an IPv6 default route.
- D.It converts the interface into a tunnel.
Why A: This configuration creates an IPv6 static route to a specific destination prefix through the named outgoing interface. In practical terms, the router is being told exactly how to reach that remote IPv6 network. This is not a default route and not a dynamic-routing statement. It is a manually defined path to one destination prefix. The key concept is recognizing the difference between a specific static route and a default route.
