300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ipv6 traffic | include tunnel
0 tunnel packets received 0 tunnel packets sent 0 tunnel packets dropped
Based on this output, what can be concluded?
⚠ Common exam trap
Cisco often tests the misinterpretation of zero counters as 'no issues' (option A) or as 'dropping all packets' (option C), when in fact zero counters simply indicate no activity on the tunnel.
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 tunnel is not carrying any IPv6 traffic.
The 'show ipv6 traffic | include tunnel' command filters the output to show only lines containing 'tunnel'. The counters for packets received, sent, and dropped are all zero, which indicates that no IPv6 packets have been encapsulated or decapsulated by any tunnel interface. This means the tunnel is not carrying any IPv6 traffic, making option B correct.
