Hi Wojciech,

The draft gives out a great support for the MAP mechanism and is nicely written. Here are some confusions while Im reading the draft. Please help me with understanding :-)

 

1, In section 7.4, the 4th paragraph:

Otherwise, the IPv6 destination address (IPv4-translateable address) MUST be derived from

the received IPv4 destination address per DMR.  The destination port number MUST be unchanged.

 

Considering the IPv6 destination address is derived from the received IPv4 destination address per DMR, why the IPv6 destination address is an IPv4-translatable address, not IPv4-converted address?

 

2, In section 7.5

   At the CE, the IPv4 source address MUST be derived from the IPv6

   source address (IPv6-converted address) as per the DMR, or as per the

   FMR.  The source port number MUST be unchanged.

 

   IPv4 Destination Address and Destination Port Number: At the CE, the

   IPv4 destination address MUST be derived from the IPv6 destination

   address (IPv6-translatable address) as per BMR.  The destination port

   number MUST be unchanged.

 

 

What is an IPv6- converted address and IPv6-translatable address? Im a little lost here

 

3, In section 6.2.1

The IPv6 source and destination addresses MUST then be derived as per Section 6 of this draft, and..

 

IMHO the super link Section 6 may be Section 7, referring to section 6.4.1 and 6.4.2. Did I understand right?

 

There are the same super link in section 6.2.2.

 

 

Please correct me if I misunderstood anything.

 

Best Regards!
