I am trying to send routes from my DHCPv6 prefix delegation server to my router using iBGP. Those delegated prefix routes on the DHCPv6 server are installed in its kernel table, such as 2001:db8:db8::/56 via <client's link-local addr>.

Wow, that's actually a really interesting way to deploy DHCPv6 PD! I've been researching how to deploy PD outside of the proprietary vendor sandboxes recently (mainly still focusing on using DHCPv6 relays with route snooping), but haven't found any good free-software options so far. Perhaps your approach could be more viable for a small network like mine. Would you mind elaborating on your setup a bit more? Thanks, --Daniel (AS212704)
