No, you don't. It works perfectly well without direct port-to-port
communication, you just have to align L3 configuration with this L2
behavior (which can be done in IPv6 but not in IPv4).
IPv6 can be made to work without on-link /64, with only DHCPv6 IA_NA
(optional) and only DHCPv6-PD. This means all communication goes via the
router which then is perfectly aligned with how the L2 looks like with
port isolation/private vlan.
