This reports whether this RSVP-TE-signaled one-directional tunnel is currently up, meaning signaling successfully completed and a forwarding path was installed, as opposed to a static tunnel's oper state which reflects only local hardware programming. An admin treats a down oper state here as potentially either a signaling failure (no path satisfying the constraints was found) or a data-plane issue, requiring a check of RSVP-TE logs in addition to the hardware, unlike the simpler diagnosis needed for a static tunnel. For example, an admin-enabled dynamic tunnel that stays oper-down should prompt checking whether RSVP-TE PATH messages are even being generated, not just whether the physical link is up.
