mplsTunnelPathInUse
mpls Tunnel Path In Use
This value denotes the configured path that was chosen for this tunnel. This value reflects the secondary index into mplsTunnelHopTable. This path may not exactly match the one in mplsTunnelARHopTable due to the fact that some CSPF modification may have taken place. See mplsTunnelARHopTable for the actual path being taken by the tunnel. A value of zero denotes that no path is currently in use or available.
