The mplsTunnelARHopTable is used to indicate the hops, strict or loose, for an MPLS tunnel defined in mplsTunnelTable, as reported by the MPLS signaling protocol, for the outgoing direction of the tunnel. Each row in this table is indexed by mplsTunnelARHopListIndex. Each row also has a secondary index mplsTunnelARHopIndex, corresponding to the next hop that this row corresponds to. The first row in the table is the first hop after the origination point of the tunnel. In case we want to specify a particular interface on the originating LSR of an outgoing tunnel by which we want packets to exit the LSR, we specify this as the first hop for this tunnel in mplsTunnelARHopTable. Please note that since the information necessary to build entries within this table are not provided by some MPLS signaling protocols, implementation of this table is optional. Furthermore, since the information in this table is actually provided by the MPLS signaling protocol after the path has been set-up, the entries in this table are provided only for observation, and hence, all variables in this table are accessible exclusively as read-only.
