Re: [IPv6] I-D Action: draft-ietf-6man-enhanced-vpn-vtn-id-06.txt

Hi all, 

This new revision addresses the comments and discussion both on the mail list and in offline reviews. Specifically, the usage and benefit of the S flag is elaborated. 

It also follow the decision of TEAS WG on the terminology alignment between VTN and NRP, so now NRP is used consistently among the enhanced VPN documents. 

The authors believe this version is in a good shape and ready for WG last call, and we would like to request for early allocation of the code point for the new HBH option as defined in the document. 

As always review and comments are welcome. 

Best regards,
Jie
