All,
The IESG reviewed the RA flags option draft and provided several
comments. In order to address those comments, I proposed the following
OLD/NEW edits to the document. I will submit a revised version of the
document to the ID editor soon. If you have issues with the proposed
changes, please let me know quickly.
OLD:
Length = 1; The length MUST be checked when processing the option
in order to allow for future expansion of this option if the need
arises.
NEW:
Length - The length MUST be checked when processing the option
in order to allow for future expansion of this option. An
implementation of this specification MUST set the Length to 1,
MUST ignore any unrecognized data, and MUST be able to recognize
the specified length in order to skip over unrecognized bits.
OLD:
During the construction/transmission, this option:
o MUST only occur in Router Advertisement messages
o MUST be the first option immediately following the Router
Advertisement message header
o MUST only occur once in the Router Advertisement message.
NEW:
During the construction/transmission, this option:
o MUST only occur in Router Advertisement messages
o MUST occur prior to any additional options associated with any
flags set in this option
o MUST only occur once in the Router Advertisement message
o MUST NOT be added to a Router Advertisement message if no flags
in the option are set
o MUST have all unused flags set to zero.
OLD:
Upon reception, a receiver processing NDP messages containing this
option:
o MUST ignore the option if it occurs in a message other than a
Router Advertisement
o MUST ignore the option if it is not the first option in the Router
Advertisement
o MUST ignore all instances of the option except the first one
encountered in the Router Advertisement message
NEW:
Upon reception, a receiver processing NDP messages containing this
option:
o MUST ignore the option if it occurs in a message other than a
Router Advertisement
o MUST ignore all instances of the option except the first one
encountered in the Router Advertisement message
o MUST ignore the option if the Length is less than 1
o MUST ignore any unknown flag bits.
OLD:
The bit fields within the option are numbered from left to right from
8 to 55 and follow the numbering of the flag bits in the RA option
described in Figure 1. Flag bits 0 to 7 are found in the Router
Advertisement message header defined in [1]
NEW:
The bit fields within the option are numbered from left to right from
8 to 55 (starting at bit offset 16 in the option) and follow the
numbering of the flag bits in the RA option described in Figure 1.
Flag bits 0 to 7 are found in the Router Advertisement message header
defined in [1]
OLD:
The assignment of new RA flags in the RA option header and for the
bits defined in the RA extension option defined in this document
require standards action or IESG approval.
NEW:
The assignment of new RA flags in the RA option header and for the
bits defined in the RA extension option defined in this document
require standards action or IESG approval [RFC2434].
Regards,
Brian
