An entry in this table represents additions to a tunnel hop visible in mplsTunnelARHopEntry. An entry is created by the signaling protocol for a signaled ERLSP set up by the signaling protocol. At any node on the LSP (ingress, transit, or egress), this table and the mplsTunnelARHopTable (if the tables are supported and if the signaling protocol is recording actual route information) contain the actual route of the whole tunnel. If the signaling protocol is not recording the actual route, this table MAY report the information from the gmplsTunnelHopTable or the gmplsTunnelCHopTable. Note that the recording of actual labels is distinct from the recording of the actual route in some signaling protocols. This feature is enabled using the gmplsTunnelAttributes object.
