Hi Marina,
Thanks for your attention and comments! I think you have proposed a good
question.
The "path label " which my draft defined is inserted into ERO list and uniquely
identifies a uni-directional path.
So one label can be added to the Ingress ERO list for the forwarding direction
and
another label with the R bit set to 0 can be added to the egress ERO list for
the reverse direction.
The two path labels can be the same or diffrent and can be binded to indentify
a bi-directional path.
I will update the draft soon and provide more details.
More comments are welcome!

主 题 ：PCEP extensions for SR-TP
Dear authors of draft-xiong-pce-pcep-extension-sr-tp,
My colleagues and I are interested in some clarifications:
According to this draft, Path label can be added as the last label in the LSP
SR-ERO list.
Each endpoint element needs 2 labels – one for forward path ID and one for
incoming path ID
Our question is – if 2 path labels can be added to the LSP SR-ERO list (one
with “R” bit) per LSP?
Path label with “R” bit set will not be added to outgoing label stack, but will
be configured in the data plane as an incoming label.
Using this approach one SR-ERO list will contain outgoing Path label as well as
incoming Path label
PCE path example:
Best regards,
Marina
