Consequently, they may continue to use addresses which are not valid for that link. This leads to packet loss and service disruption. This document proposes a mechanism to mitigate this issue. Routers are advised to send Router Advertisements containing distinct Prefix Information Options (PIOs) from different link-local addresses. This, in conjunction with RFC6724 (Default Source Address Selection) Rule 5.5 and RFC8028 (first-hop selection requirements), enables hosts to detect prefix changes more rapidly and select the correct source address, thereby improving the robustness of SLAAC.}, }
