300-410 Practice Question: Which THREE commands can be used to verify IPv6…
Which THREE commands can be used to verify IPv6 traffic filtering and uRPF operation on a Cisco IOS-XE router? (Choose THREE.)
⚠ Common exam trap
Cisco often tests the distinction between commands that show configuration/status (like 'show ipv6 interface') versus those that show operational statistics or neighbor tables, leading candidates to mistakenly select 'show ipv6 traffic' or 'show ipv6 neighbors' for verification tasks.
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
✓
show ipv6 interface
The 'show ipv6 interface' command displays IPv6 interface configurations, including whether IPv6 unicast reverse path forwarding (uRPF) is enabled and its strict or loose mode. It also shows access-group information for IPv6 traffic filtering applied to the interface, making it essential for verifying both uRPF and ACL application.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show ipv6 interface
Why this is correct
Correct. This command shows whether an IPv6 access-group or uRPF is applied on the interface, including packet statistics.
- ✓
show ipv6 access-list
Why this is correct
Correct. Displays the configured IPv6 access-lists with hit counts, useful for verifying if traffic is being matched.
- ✓
show ipv6 route
Why this is correct
Correct. uRPF uses the FIB, and 'show ipv6 route' shows the routing table entries needed for uRPF verification.
- ✗
show ipv6 traffic
Why it's wrong here
Incorrect. This command shows aggregate IPv6 packet statistics (e.g., total packets sent/received), not per-interface filtering or uRPF status.
- ✗
show ipv6 neighbors
Why it's wrong here
Incorrect. This shows the IPv6 neighbor discovery cache (MAC addresses), not related to traffic filtering or uRPF.
