The IESG has received a request from the IPv6 Operations WG (v6ops) to consider the following document: - 'Using Conditional Router Advertisements for Enterprise Multihoming' <draft-ietf-v6ops-conditional-ras-04.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-05-21. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document discusses the most common scenarios of connecting an enterprise network to multiple ISPs using an address space assigned by an ISP. The problem of enterprise multihoming without address translation of any form has not been solved yet as it requires both the network to select the correct egress ISP based on the packet source address and hosts to select the correct source address based on the desired egress ISP for that traffic. The "ietf-rtgwg- enterprise-pa-multihoming" document proposes a solution to this problem by introducing a new routing functionality (Source Address Dependent Routing) to solve the uplink selection issue and using Router Advertisements to influence the host source address selection. While the above-mentioned document focuses on solving the general problem and on covering various complex use cases, this document describes how the solution proposed in the "ietf-rtgwg-enterprise-pa- multihoming" draft can be adopted for a limited number of common use cases. In particular, the focus is on scenarios where an enterprise network has two Internet uplinks used either in primary/backup mode or simultaneously and hosts in that network might not yet properly support multihoming as described in RFC8028.
