Re: [Idr] Fw: Re: New Version Notification for draft-xie-idr-mpbgp-extention-4map6-00.txt

Hi Chongfeng

I see in the 4map6 path attribute it defines forwarding type on the egress
PE for encapsulation or translation.

This draft talks about the BGP aspects of the 4map6  service, however there
seems to be another big piece to the puzzle which is the mapping table on
the PE.

Would there be a framework document that goes over the details of the
overall solution for how the mapping db on the egress PE db data structures
is built  and how that would be built for both translation and
encapsulation options.

Since this mapping is prefix based and not traditional 1-1 or 1-many NAT or
PAT overload or even PT style I wonder how this would all work.

I am guessing that the framework draft would be in 6MAN.

Thanks

Gyan
