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 tunnel brief
Tunnel2: IPv6/IP, intf id 0/0/2, 6to4, mtu 1280 Source: 192.168.1.1 (GigabitEthernet0/0) Destination: 192.168.2.1 Tunnel transport: IPv4
Based on this output, which statement is correct?
⚠ Common exam trap
Cisco often tests the distinction between automatic 6to4 tunnels (where the destination is derived from the IPv6 address) and manually configured tunnels (where both source and destination are explicitly set), leading candidates to assume any tunnel with '6to4' in the output is correctly configured.
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
✓
This tunnel is actually a manually configured IPv6/IP tunnel, not a 6to4 tunnel.
The output shows a manually configured IPv6/IP tunnel because it specifies both a source and destination IPv4 address. In a true 6to4 tunnel, the destination is automatically derived from the 6to4 prefix (2002::/16) and the destination IPv4 address, not statically configured. The presence of a static destination address indicates this is a manually configured tunnel, not a 6to4 tunnel.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
This is a correctly configured 6to4 tunnel.
Why it's wrong here
6to4 tunnels do not have a configured destination; the destination is derived from the 6to4 prefix.
- ✓
This tunnel is actually a manually configured IPv6/IP tunnel, not a 6to4 tunnel.
Why this is correct
The presence of a specific destination address indicates a manual tunnel; 6to4 tunnels have no configured destination.
- ✗
The tunnel is an ISATAP tunnel.
Why it's wrong here
ISATAP tunnels use a different interface type and addressing.
- ✗
The tunnel is in an up/up state and passing traffic.
Why it's wrong here
The output does not show interface status; only configuration parameters.
