About section 3.2 , there is the following
If the section is an LSP, this information MAY be implied by
the LSP label or, if the LSP payload is MPLS-labeled, by the setting
of the S bit. Additional labels MAY also be used if necessary
distinguish different payload types"
IMO, if the client traffic of section layer is MPLS-labeled,
the S bit of
section label must be set 1.
if my understanding is true, maybe violate MPLS-TP
in my memory,only S bit of the lowest label should
be set 1 in MPLS Label stack,
there can be only one S-bit set in a label stack.
maybe i misunderstand the sentence? I hope it
can clarify this paragragh clearly.
