Re: I-D ACTION:draft-shiomoto-ccamp-lsp-hierarchy-bis-00.txt
i don't think the issues of advertising an LSP as a TE link in another
instance of the control plane than the one used for creating the LSP - ditto
"[HIERAR] did not consider scenarios where an LSP is created (and
maintained) by one instance of the GMPLS control plane, and is used as a
(TE) link by another instance of the GMPLS control plane."
is only a matter of indicating to which instance this advertisement
should be done;
now, in addition to the "routing" part, there is the whole discussion
about the maintenance of the (inherited) TE link - as we are speaking
here about separate instance - some specific mechanism may be needed
otherwise after their creation there may be no easy way to communicate
another more specific question on this document, what is the definition
of the value space for the "Target Control Plane Instance" ?
a last point, section 4 mentions
"This is not believed to be an issue as an informal survey indicated
that dynamically signalled numbered FAs had not been deployed. Indeed
it was the attempt to implement numbered FAs that gave rise to the work
on this document." ... is there a general feeling that having this
mechanism will make dynamically triggered numbered FA a reality ?

Title : Advertisement of hierarchical and stitchable LSPs as TE Links

This document addresses topics related to hierarchical and stitched
Label Switched Paths (LSPs). It describes extensions to allow an
egress to identify that an LSP will be used as a dynamically signaled
Forwarding Adjacency LSP (FA-LSP) in the case of numbered FA's. In
addition, the document addresses the issue of how to indicate that an
LSP should be advertised as a TE link into a different instance of
the control plane and how to identify the instance that should be
