An entry in this table represents a protected tunnel LSP together with its detour tunnel instance. An entry in this table is only created by an SNMP engine as instructed by an MPLS signaling protocol. The entries of this table are present in all LSRs on the path of the detour LSP. The objects mplsFrrOne2OnePlrSenderAddrType and mplsFrrOne2OnePlrSenderAddr can be modified after the row is created. The objects mplsFrrOne2OnePlrTunnelIndex, mplsFrrOne2OnePlrTunnelDetourInstance, mplsFrrOne2OnePlrTunnelIngressLSRId, and mplsFrrOne2OnePlrTunnelEgressLSRId have the same values as the objects mplsTunnelIndex, mplsTunnelInstance, mplsTunnelIngressLSRId, and mplsTunnelEgressLSRId of the detour tunnel instance created in the mplsTunnelTable (MPLS-TE-STD-MIB). The entries in this table will be deleted when the corresponding entries in the mplsTunnelTable are deleted.
