this is not what i say. i am concerned in stating beforehand
RFC 3945 (GMPLS Arch.) is not applicable to Ethernet. Why the
doc. does not deliver any tangible explanation.

so you seem to agree with me. departing from RFC 3945 makes
little sense. it would have been interesting to see the doc
delivering a FIT of the GMPLS protocol arch. blocks and, in
particular, label allocation and distribution for Ethernet.
