Reviewer: Sheng Jiang Review result: Has Issues Reviewer: Sheng Jiang Review result: Has Issues I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. This Informational document describes a mechanism that uses the conditional Router Advertisements for Enterprise Multihoming in which an enterprise network up-links to multiple ISPs using an address space assigned by an ISP. Major issue: no. Minor issue: There are many unused reference. However, they are not simple Nits and cannot be fixed by deleting them from reference list. Many of these unused reference are really relevant and should have some content to describe the relationship with the mechanism or scenario of the document, such as RFC6296 NAT66, etc. Regards, Sheng
