Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 5

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

Answer options

• A. traceroute <tunnel destination IP>
• B. show mpls traffic-engineering tunnels
• C. Ping <tunnel destination IP>
• D. traceroute mpls ipv4 <tunnel destination>

Correct answer: D

Explanation

The correct answer is D, as the command 'traceroute mpls ipv4 <tunnel destination>' specifically traces the path of MPLS traffic engineering tunnels, providing insights into the tunnel's route. Options A and C are general traceroute and ping commands that do not focus on MPLS TE tunnels, while B provides information about the tunnels but does not trace the path.
