The Path Computation Element Communication Protocol (PCEP) enables
communications between a Path Computation Client (PCC) and a PCE, or
between two PCEs. RFC 5440 defines the Include Route Object (IRO) to
specify network elements to be traversed in the computed path. The
specification does not specify if the IRO contains an ordered or
unordered list of subobjects. During recent discussions, it was
determined that there was a need to define a standard representation
to ensure interoperability. It was also noted that there is a
benefit in the handling of an attribute of the IRO's subobject, the L
bit.
This document updates RFC 5440 regarding the IRO specification.
This document is a product of the Path Computation Element Working Group of the IETF.
This is now a Proposed Standard.
