2.5.2.4. LABEL-REQUEST TLV
The LABEL-REQUEST TLV indicates the switching capability and encoding
type of the following label restriction list for the endpoint. Its
format and encoding is the same as described in [RFC3471] Section 3.1
Generalized label request. The LABEL-REQUEST TLV use TLV-Type=TBA.
The Encoding Type indicates the encoding type, e.g., SONET/SDH/GigE
etc., of the LSP with which the data is associated. The Switching
type indicates the type of switching that is being requested on the
endpoint. G-PID identifies the payload. This TLV and the following
one are introduced to satisfy requirement 13 for the endpoint. It is
not directly related to the TE-LSP label request, which is expressed
by the SWITCH-LAYER object.
On the path calculation request only the Tspec and switch layer need
to be coherent, the endpoint labels could be different (supporting a
different Tspec). Hence the label restrictions include a Generalized
label request in order to interpret the labels. This TLV MAY be
ignored, in which case a PCRep with NO-PATH should be responded, as
described in Section 2.5.1.
