My ISP gives out ipv6 with a prefix delegation of /64. Is it possible to create multiple ipv6 /68 or /69 subnets on my network? If yes, then how?
I have the ipv4 subnets working to my satisfaction. However, only my main LAN subnet is fully working on ipv6 with internally routable addresses (eg. fda6:... ) and externally routable addresses (eg. 2401:... ). The other subnets only get locally routable addresses. I understand that this is likely that the router / odhcpd is fully adhering to specifications and refusing to create subnets of /68.
The ISP seems to be marketing driven rather than technically driven, providing mobile, fiber, and TV services. Therefore I see little chance of getting them to change.
