An entry in this table is created by an LSR for every interface capable of supporting MPLS. Each entry in this table will exist only if a corresponding entry in ifTable exists. If the associated entry in ifTable is deleted, the corresponding entry in this table must also be deleted shortly thereafter. The entry with index 0 represents the per-platform label space and contains parameters that apply to all interfaces that participate in the per-platform label space. Other entries defined in this table represent additional MPLS interfaces that may participate in either the per-platform or per-interface label spaces, or both. Additional information about label space participation of an interface is provided in the description clause of mplsInterfaceLabelParticipationType.
