1. Errata:

    Page 18, ICMP Fields/Code: should be 0, 1, 2, 3; 
    Page 27, 6.3.3 "Type value for FBACK is 10", should be changed to 
                           "Type value for FNA is 10";

2. Questions, welcome any comments. :)

   Page 19, Code Value =0, isn't it a must to provide New Prefix Information? 
                 otherwise, no way to construct New CoA.

   Page 30, The LLA option, if the length is in 8 octets, there is no way to figure
                 out the valid length of link-layer length. for example, 802.3, link-layer
                 addr length is 6 octets, the valid length of the entire option is 9 octets,
                 but the length field must be filled with 2, because 9 is not a multiple of
                 8. Shouldn't we use PAD options, instead of  specify the link layer length
                 in this way?

   Page 31 6.4.4. for NAACK options,  if new Care-of address is supplied,
                is it implies that the nCoa's life-time is the same
                as the life time for the Prefix in the router advertisement? 
                If so, I think it's better to state that.
