The WG Last Call has ended. I do have a couple minor comments.

   1. Section 1 list the advantages for setting up an LSP over a TTZ as
opposed 
      to an area. The details of this are not described in the document so
this 
      should either be removed or the document should explicitly state the
details
      of LSP setup are out of scope.

   2. In section 11.2, I can see some race conditions if different TTZ
status is 
      configured on different routers in the TTZ during the
migration/rollback 
      period. This is addressed by saying a warning message will be issued
if 
      this occurs. How is this detected and will the conflicting operation
be 
      rejected? 

   3. I guess one misconfigured router (no TTZ ID configured) will keep
migration 
      to TTZ from occurring. What happens if a misconfigured router is
introduced 
      on a broadcast link? Do all routers on the link revert to non-TTZ
operation? 

I also have a number of editorial comments but will send those offline.

Thanks,
Acee
