Summary:
This draft is basically ready for publication, but has nits
that should be fixed before publication.

Comments:
This draft extends GMPLS routing and signaling to support the
operation of GMPLS Multi-Layer/Multi-Region Networks.  One needs to be
a GMPLS expert to fully understand this draft - although, I'm not a
GMPLS expert, the draft reads reasonably well.  All of these comments
are minor.

The IACD sub-TLV formats for OSPF and IS-IS appear to be identical.  If
they are in fact identical, a single ASCII text diagram should be used
for both.

The description of the IACD sub-TLV format does not describe the
Max LSP Bandwidth fields.  At a minimum the units and/or encoding of
these fields should be described here, even thought the full
specification may be elsewhere.

Please add the values for Type and Length for the XRO SC subobject
into the ASCII figure in Section 4.1.1 .

Section 4.1.2 defines a new subobject by making minor changes to an
existing one in another RFC; a complete ASCII diagram of the new
subobject would be helpful - please add one.

Sections 5.1.4, 5.2.1 and 8 have me confused about the Attributes Flags TLV:
- Section 5.1.4 defines an Attributes Flags TLV here
- Section 5.2.1 points to RFC 5420 for what's apparently a different
	Attributes Flags TLV and defines a Pre-Planned LSP flag in
	that TLV.
- Section 8 then apparently instructs IANA to put that bit into the
	Attributes Flags TLV defined in Section 5.1.4 .
Something appears to be wrong with this combination - what was
the intent?  If these two TLVs are the same, or share a common bit
assignment registry, that should be stated.

idnits 2.12.00 found three nits:

  == The page length should not exceed 58 lines per page, but there was 1
     longer page, the longest (page 1) being 62 lines

  ** There are 144 instances of too long lines in the document, the longest
     one being 1 character in excess of 72.

  == Line 781 has weird spacing: '...ndwidth  is st...'
