When configuring traffic engineering tunnels in Cisco MPLS core network, you see the traffic is not taking the expected path in the core. Which command do you use to quickly check path of a TE tunnel?

The `traceroute mpls ipv4` command traces the MPLS forwarding path to a destination IP, but it does not specifically display the configured and operational path of an MPLS Traffic Engineering tunnel itself.

The `ping` command only verifies reachability to a destination IP address and does not provide any information about the path taken or the TE tunnel's operational status.

The `show mpls traffic-engineering tunnels` command provides detailed information about all MPLS TE tunnels, including their operational status, configured path, actual path taken, and associated statistics. This output is essential for troubleshooting and verifying the expected traffic flow through the core network via TE tunnels.

The standard `traceroute` command traces the IP forwarding path and does not provide MPLS-specific path information or details about TE tunnels.
