Hi Dhruv, Quan, Thanks for taking care of my review. That work for me.

Backward Compatibility The LSP-EXTENDED-FLAG TLV defined in this document does not introduce any backward compatibility issues. An implementation that does not understand or support the LSP-EXTENDED-FLAG TLV will silently ignore the TLV as per [RFC5440]. It is expected that future documents that define bits in the LSP-EXTENDED-FLAG TLV will also define the error case handling required for missing LSP-EXTENDED-FLAG TLV if it MUST be present. Further, any additional bits in the LSP-EXTENDED-FLAG TLV that are not understood by an implementation would be ignored. It is expected that future documents that define bits in the LSP-EXTENDED-FLAG TLV will take that into consideration. > Nits/editorial comments: > Introduction: > OLD > The bit value 4 is assigned in [RFC8281] for create for PCE-Initiated > LSPs. > New > The bit value 4 is assigned in [RFC8281] for creation and deletion for > PCE-Initiated LSPs. > > Quan>>Thanks, will revise it in the new version. > Dhruv: The flag is called "create" and the new change could lead to confusion. I would rather we rephrase this to - "The bit value 4 is assigned in [RFC8281] to identify PCE-Initiated LSPs." Thanks!
