Document: draft-ietf-softwire-multicast-prefix-option-11 Reviewer: Roni Even Review Date:2017-1-9 IETF LC End Date: 2017–1-12 IESG Telechat date: Summary: This draft is almost ready for publication as a standard track RFC. Major issues: Minor issues: 1. In section 4 first paragraph say “DHCP servers supporting OPTION_V6_PREFIX64 should be configured with U_PREFIX64 and at least one multicast PREFIX64 (i.e., ASM_PREFIX64 and/or SSM_PREFIX64).” From the rest of the section I understand that for SSM deployments both U_PREFIX64 and SSM_PREFIX64 MUST be configured. What is the reason for “should” in the first paragraph? Are there cases where ASM_PREFIX64 or ASM_PREFIX64 and SSM_PREFIX64 are specified and there is no need to specify U_PREFIX64, maybe these cases should be described. Nits/editorial comments: 1. RFC2119 keywords in the document are sometime capitalized and sometime not. I think it will be good to have consistency and if they do not intend to have RFC2119 semantics some other words should be used
