RFC6085 update to rfc2464bis

[Bob Hinden <[e-mail]>]

Hi,

Based on update from RFC6085 I added two paragraphs to Section 7 of <draft-hinden-6man-rfc2464bis-01>.  These are:

> 7.  Address Mapping -- Multicast
> 
>    An IPv6 packet with a multicast destination address DST, consisting
>    of the sixteen octets DST[1] through DST[16], is transmitted to the
>    Ethernet multicast address whose first two octets are the value 3333
>    hexadecimal and whose last four octets are the last four octets of
>    DST.
> 
>                   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
>                   |0 0 1 1 0 0 1 1|0 0 1 1 0 0 1 1|
>                   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
>                   |   DST[13]     |   DST[14]     |
>                   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
>                   |   DST[15]     |   DST[16]     |
>                   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

   An IPv6 multicast packet may also be mapped to a unicast Ethernet
   Link layer address as defined in Section 6.

   An IPv6 node receiving an IPv6 packet with a multicast destination
   address and an Ethernet link-layer unicast address must not drop the
   packet as a result using of this form of address mapping.

While RFC6085 isn’t exactly clear about the change it wants in RFC2464, I think this is about right.

Comments?

Thanks,
Bob
