This object should be interpreted along with the object fsLsppPathType. This object points to the correponding path details. If fsLsppPathType is ldpipv4(1) or ldpipv6(2), then this object MUST contain zeroDotZero or point to an instance of the mplsFTNEntry indicating the LDP-based LSP associated with this ping or traceroute operation. If fsLsppPathType is rsvpipv4(3) or rsvpipv6(4), then this object MUST contain zeroDotZero or point to an instance of the mplsTunnelEntry indicating the RSVP-based MPLS TE tunnel associated with this ping or traceroute operation. If fsLsppPathType is fec128pw(5) or fwc129pw(6), then this object MUST contain zeroDotZero or point to an instance of the pwEntry indicating the FEC128 or FWC 129 based Pseudowire associated with this ping or traceroute operation. If fsLsppPathType is mep(6), then this object MUST contain zeroDotZero or point to an instance identifying the MEP entity configured for monitoring the MPLS-TP path associated with this ping or traceroute operation. If this object points to a conceptual row instance in a table consistent with fsLsppPathType but this instance does not currently exist then no valid path is associated with this ping or traceroute entry. If this object contains zeroDotZero then no valid path is associated with this ping or traceroute entry till it is populated with a valid pointer consistent with the value of fsLsppPathType as explained above.
