This object reports whether this router supports OSPF traffic engineering extensions, which use Opaque LSAs to flood link bandwidth and constraint information used by technologies like MPLS-TE for constrained-path computation. It matters directly for any MPLS-TE deployment plan; an admin cannot rely on this router to participate in TE-aware path computation if this reports false, regardless of whether Opaque LSA support itself is present. A network team planning to roll out TE tunnels through this router should verify this is true before assuming the router will correctly flood the needed TE link attributes.
