Hi Pushpasis,

Thanks for this draft. IMO It is reasonable to extend BGP-LS for the distribution of node admin tags. Here are a few comments:

1. page 3, it says:

"a new Node Attribute TLV to be carried in the corresponding BGP-LS Node NLRI is proposed", 

 Maybe it is more accurate to say " to be carried with the corresponding BGP-LS Node NLRI", as this new TLV is carried in the BGP-LS attribute.

2. section 3.1 proposes to put admin tags with different scopes into separate node admin tag TLVs, and the L bit is used to identify the scope. This way all the node admin tags with per-area scope would be packed into the same TLV. While the ABRs in OSPF can participate in multiple areas, and the same node admin tag may have different meanings in these areas, in such case some mechanism may be needed to separate the per-area admin tags of different areas into separate node admin tag TLVs. 

Best regards,
