It is an interesting draft, and also a useful draft to me.
 
Regarding the motivation, I think it is valid to do so to help IPv6 migration.
The draft is well written, and the logic is clear, so I support the adoption. It has reached a good point to be a beginning of a WG item.
 
Some comments:
Nits:
1. Introduction: s/[I-D./draft-ietf-v6ops-framework-md-ipv6only-underlay]/ [I-D.draft-ietf-v6ops-framework-md-ipv6only-underlay]
I am not sure what kind of method the authors are using to write this draft. But I recommend to use markdown to rewrite it. In this way, you can avoid a lots problems of editing, such as this one. We cannot click it and jump to the referenced draft.
[CF]: We will erase the nits and try to use the makedown you recommeded. 
 
Comments:
2. Error handling and security sections should be enhanced, you may meet the same requests in later stage in WGLC. I am handling similar problem of several drafts now 
[CF]: OK, it will be definitely enhanced later on.
 
Suggestions:
3. also, the authorship should be handled early. I have met some troubles on this already, it is always not easy to handle that, so it will be good to do it early.
[CF]:  This should be handled early, thank you for you advice, 
 
Thanks,
Cheng
 


Best regards
Chongfeng

Hi All,
I have read the draft and I support its adoption.
I agree with the need to define MP-BGP extension for  IPv4/IPv6 mapping advertisement in order to enable IPv4 service delivery in multi-domain IPv6-only underlay networks. It can help network operators that operate whole multi-domain networks or even single domains of multi-domain networks. 
 
Regards,
 
Giuseppe
