Uniquely identifies a set of tunnel instances between a pair of ingress and egress LSRs. Managers should obtain new values for row creation in this table by reading mplsTunnelIndexNext. When the MPLS signalling protocol is rsvp(2) this value SHOULD be equal to the value signaled in the Tunnel Id of the Session object. When the MPLS signalling protocol is crldp(3) this value SHOULD be equal to the value signaled in the LSP ID.
