Q: 9
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?

C , "show mpls traffic-engineering tunnels" is what actually shows the TE tunnel path, not just the IP route. D is a trap since it only checks underlay IP hops, missing MPLS specifics. Pretty sure it's C unless they asked differently.
Nah, I don’t think it’s D. C gives you the detailed tunnel path end-to-end, including all hops along the LSP. D just shows basic IP routing, not the actual MPLS TE tunnel info. Pretty sure C is what you want here, unless they were asking about plain IP routing. Anyone disagree?
C imo. "show mpls traffic-engineering tunnels" reveals the label switched path, not just IP hops. D is tempting but misses MPLS tunnel details. Unless the question wanted plain IP trace instead, C's right here.
Probably C. The "show mpls traffic-engineering tunnels" command lists the actual path the TE tunnel takes, not just the IP route. Tunnel info like this won't appear with a regular traceroute. Correct me if I'm missing some IOS XR variation.
Option D, Seen this command in some sample labs and exam reports for checking tunnel issues.
A is wrong, C. "show mpls traffic-engineering tunnels" gives the active TE tunnel path, not just IP hops.
C in this case, since
show mpls traffic-engineering tunnels provides the LSP/path details for TE tunnels directly. D just traces normal IP hops, not the actual MPLS TE path. Pretty sure that's what they want here, but let me know if you see differently.C , because "show mpls traffic-engineering tunnels" gives the actual MPLS TE tunnel path info, not just standard route hops. D would only show IP layer, not the LSP. Pretty confident about this but open to corrections.
Its C, that's what the official exam guide says for checking actual TE tunnel paths.
C tbh, "show mpls traffic-engineering tunnels" actually shows you the exact path the TE tunnel takes across the MPLS core including the hops in the label switched path. D (traceroute) only gives you IP hops, it doesn't reflect the MPLS label switching so you'll miss what the TE tunnel's really doing. That's why C fits best unless IOS version does something weird. Anyone disagree?
Be respectful. No spam.
