   Dimitri,

   I understand the sentence "The node attribute TLV must appear in exactly one TE LSA originated by a router." as meaning that a router is not allowed to originate multiple LSAs specifying a node attribute TLV.

   Thanks for your quick answers,
   Rémi

Don't we say the same thing ? Quoting this doc.:
 
 " The node attribute TLV must appear in exactly one TE LSA originated
   by a router. Further only one node attribute TLV must be advertised
   in such a LSA. A node attribute TLV must carry at most one Node IPv4
   Local Address sub-TLV and at most one Node IPv6 Local Address sub-
   TLV."
 
Hence, to your question:

  

Should a Local TE Router-ID sub-TLV be encoded 
*before* each Node IPv4/IPv6 Local Prefix Sub-TLV? 
    

it is a one to one correspondance in each of these LSAs.
-d.

   Hi Dimitri,

   I thought about it, but 
draft-ietf-ospf-te-node-addr-05.txt section 
4.2 states "The node attribute TLV must appear in exactly one TE LSA 
originated by a router. Further only one node attribute TLV must be 
advertised in such a LSA." So it does seem possible for a router to 
advertise multiple LSAs specifying a node attribute TLV.

   Thanks,
   Rémi

hi remi: the encoding follows 
      

http://www.ietf.org/internet-drafts/draft-ietf-ospf-te-node-ad
dr-05.txt 
<http://www.ietf.org/internet-drafts/draft-ietf-ospf-te-node-a
ddr-05.txt>; hence, you will find only one TE Router ID 
sub-TLV (together with one Node IPv4 / IPv6 Local Prefix 
sub-TLV) per top level node attribute TLV per opaque LSA and 
have multiple TE LSAs.
    

 
thanks,
-dimitri.

	  Hi CCAMP, 
	
	  One question about 
      

draft-ietf-ccamp-gmpls-ason-routing-ospf-08.txt. 
    

	  This draft defines a new Node-Attribute sub-TLV 
      

(Local TE Router-ID sub-TLV) as "optional sub-TLV for scoping 
reachability per TE Router-ID". 
    

	  How does this scoping occur when a router advertises 
      

reachability information on behalf of multiple TE Router IDs? 
    

	  Should a Local TE Router-ID sub-TLV be encoded 
      

*before* each Node IPv4/IPv6 Local Prefix Sub-TLV? 
    

	  
	  Regards, 
	  Rémi
