This value reports whether this transit LSP segment is currently up and actually forwarding labeled traffic through this midpoint router, as opposed to merely being administratively permitted. Since a transit tunnel has no head-end control plane visibility of its own, this oper state is the fastest way for an admin to confirm the RSVP-TE reservation successfully installed a forwarding entry on this specific hop rather than just being pending. For example, an oper state of down on a transit row while the ingress tunnel reports up would tell the admin the LSP setup failed or link went down specifically at this node, not at the source.
