300-410 Practice Question: Which THREE commands can be used to verify the…
Which THREE commands can be used to verify the operational state and configuration of an IPv6 tunnel? (Choose THREE.)
⚠ Common exam trap
Cisco often tests that candidates confuse general routing table commands (show ip route, show ipv6 route) with interface-specific verification commands, leading them to select options that show reachability but not the tunnel's operational state or configuration.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show interfaces tunnel 0
Option A, 'show interfaces tunnel 0', is correct because it displays the operational state (up/down) of the tunnel interface along with encapsulation, line protocol status, and packet counters, which directly verifies the tunnel's operational state. Option B, 'show ipv6 interface tunnel 0', is correct because it shows the IPv6-specific configuration and status of the tunnel interface, including the IPv6 address, link-local address, and whether IPv6 is enabled on that interface. Option C, 'show running-config interface tunnel 0', is correct because it displays the configured tunnel parameters such as tunnel source, tunnel destination, tunnel mode (e.g., ipv6ip), and other interface settings, verifying the tunnel's configuration. Option D, 'show ip route', is not correct because it only displays the IPv4 routing table and does not provide tunnel-specific operational or configuration details. Option E, 'show ipv6 route', is not correct because it only shows the IPv6 routing table and does not verify the tunnel interface's state or configuration.
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 interfaces tunnel 0
Why this is correct
`show interfaces tunnel 0` reports line and protocol status, tunnel source and destination addresses, and encapsulation, directly confirming the operational state and configuration of the IPv6 tunnel interface. It satisfies the stem's verification requirement by exposing both the tunnel's current state and its configured parameters in a single command.
- ✓
show ipv6 interface tunnel 0
Why this is correct
`show ipv6 interface tunnel 0` displays the tunnel interface's IPv6 operational state, including link-local and global addresses, interface status, and MTU, directly satisfying the stem's requirement to verify operational state and configuration of the IPv6 tunnel.
- ✓
show running-config interface tunnel 0
Why this is correct
`show running-config interface tunnel 0` displays the tunnel interface's configured parameters, including tunnel mode, source and destination addresses, and IPv6 addressing. This directly satisfies the stem's requirement to verify configuration, complementing operational-state commands such as `show interface tunnel 0` and `show ipv6 interface tunnel 0`.
- ✗
show ip route
Why it's wrong here
The IPv4 routing table shows tunnel endpoints as next hops but reveals nothing about tunnel interface state, encapsulation or configuration. `show ip route` would be the choice when verifying reachability of a tunnel's transport or destination networks, not the tunnel itself.
- ✗
show ipv6 route
Why it's wrong here
`show ipv6 route` displays the IPv6 routing table, including tunnel routes, but not interface line-protocol state, tunnel source/destination or encapsulation settings. It would be correct when confirming IPv6 reachability through a tunnel, not when verifying the tunnel's operational configuration.
