I need to configure prefix delegation on PPPoE. What is the best DHCPv6 server implementation for this? So far I checked the following:
isc-dhcp-server - doesn't work with PPP interfaces
dibbler - works, but needs all the interfaces to be present before the server starts so hacks in ipv6-up/down scripts are needed
dhcp6s (wide) - works, but delegates prefixes based on DUID only
dnsmasq - doesn't do PD
