Hesham, Section 3 looks good. On Section 11, I've got the following comments: 1) Much of what is in the Section 11.1 seems a summary of RFC 3756. On the one hand, I suppose it is helpful to refresh the reader's memory, on the other, it could shorten the spec and make for less reading. It's just

This issue was discussed on the list and in the last meeting. There were two sub issues: 1. How does a host configure an address? 2. Inconsistency with ADDRARCH We agreed that (1) is out of scope for 2461bis and is more relevant for address configuration mechanisms. (2) was discussed in the me

2004-06-14 Thread Soliman Hesham
As far as 2461bis is concerned it is stated in the current draft that setting the M flag implies that DHCPv6 is used for address config. If the O flag is set, the draft refers to DHCPv6 for other config parameters. RFC 3315 is also referenced. Please see section 4.2, definition of the M and O fl
