If DHCPv6 is used to request Prefix Delegation (PD), AAISP reply with one /64 block. OpenWrt uses this to set the LAN address and netmask, and then enables routing from '''just this block''' from LAN to WAN. Any other /64 blocks routed to you won't be able to send packets to the Internet. To quote from [https://openwrt.org/docs/guide-user/network/routing/basics OpenWrt Wiki - Routing basics] ''Note that by default OpenWrt announces IPv6 default route only for GUA and applies source filter for IPv6 that allows routing only for prefixes delegated from the upstream router.'' In my case, I have 2001:8b0:xxxx:4534::/64, ...:4535/64, ...:4536::/64 and ...:4536::/64 routed to me, but only 4534:: is routed back.
