I may be missing something simple, but am scratching my head. I have set enabled the DHCPv6 server on my Vigor 2860, and it appears to be giving ipv6 addresses to some devices on my LAN. The addresses show on the devices - a linux desktop and android phone and tablet, for example. However, the DHCPv6 IP Assignment Table under 'Diagnostics' of my Vigor 2860 is empty. The v4 assignments are all visible. Does anyone know if this is expected behaviour?

On my 2862 the DHCPv6 assignment table when showing "ALL LANS" indicates that 4 IPs have been assigned in LAN 1. If I choose LAN 1 instead of "ALL LANS" the table is empty. Go figure.
