Hi authors, I’ve spent some time on reading this document and I think it is a good piece of work to define a new DHCPv6 option to carry the IPv6 prefixes. Here are several comments.
1. Could you please explain why the ‘DHCPv6 server supporting OPTION_V6_PREFIX64 should be configured with U_PREFIX64 and at least one ASM_PREFX64 or one SSM_PREFIX64’ in section 4? This statement confuses me because when the ASM mode is supported, there is no need to configure the U_PREFIX64. 2. I do not really understand the following part in section 4. 'When ASM_PREFIX64 and SSM_PREFIX64 are configured, the length of these prefixes must be /96.' You have mentioned in the section 3 that those prefixes are likely to be /96 not must be. Could you do me a favor to explain it more specifically? 3. Would you please describe the following part in section 5 in detail? 'if both SSM and ASM modes are supported' The modes above are supported by the server or the client? 4. It seems that there is not a clear part that indicating which DHCPv6 message will carry the new DHCPv6 option. Do you think it is more appropriate to add a separate part to discuss this issue especially when the client is at the DHCP renew stage? 5. I also find that there is a spelling mistake in the following part in section 5. 'the Pv4 multicast address is inserted in the last 32 bits of the IPv4-embedded IPv6 multicast address.' Where the second word should be 'IPv4'. Best regards, Linhui Sun [email protected]
