Re: One question about draft-ietf-ccamp-gmpls-ason-routing-ospf-08.txt

  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
