The vRtrMplsTunnelCHopTable is used to hold the CSPF
path for a detour LSP. Each entry indicates a single
hop.
Primary index is the vRtrMplsTunnelCHopListIndex which associates
multiple entries (hops) in the vRtrMplsTunnelCHopTable to a single
mplsTunnelEntry specified in the mplsTunnelTable.
The first row in the table is the first hop after the
origination point of the tunnel.
