Declined Omada multiple V-LAN Limitations for dynamically allocated IPV6 when ISP provider has /64 prefix
Both my Business and Home office use non-static (dynamic) ISP nework service that provider only /64 prefix IPV6 support .
Omada appears to only provide a hinted dynamic Prefix (Slaac/DHCP or Slaac/RDNSS) to the first VLAN setup, after that all other VLANS give error that prefix is in-use.
Being a small business I will never need more than 60-100 address so I am not in need of a more expensive ISP provided service that would provide a IPV6 prefix length less than /64 that appears Omada would then allow multiple VLAN support using dynamic IPV6 Prefix hint.
So my question is why can't Omada provide a means to use a ISP /64 IPV6 Prefix space across multple V-LANS? I tried manually setting this up using DHCPV6 on each VLAN however it once again would only allow the setup on the first V-LAN and then give the error prefix already in-use ON THE NEXT V-LAN..
I understand that the norm is to have a ISP service that provides a /56 (48-60) type Prefix that can then be split-up on Omada V-LANs by defining a unique remaining prefix segment on each VLAN to complete /64 size.
Would like to ask if it is possible to work with a /64 ISP prefix and allow the use of defining another uniquie segmant for each VLAN with a final Prefix length of lets say /72?
Example: ISP hinted prefix 2606:4700:4898:2222/64, Omada using /64 PREFIX hint but allowing a /72 prefix . VLAN-1 2606:4700:4898:2222::01/72, VLAN-2 2606:4700:4898:2222::02/72, ETC
