It helps me to run dhcp6 and stop failing immediately, but it then fails on reservations. For example when I boot to linux it assigns ipv6 address honoring the reservation, but it also creates a lease. When I reboot to linux I get ipv6 address from the pool assigned since it thinks the reservation is not possible, since the lease exists.</div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);">Is there some possibility to either not crating leases for reservations or strictly honor reservations even when lease exists and overwrite it?</div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);">Thanks</div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);">Marek</div><div style="font-family: Arial; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div class="protonmail_quote">
