Dynamic IPv6 Prefix Delegation

Hello,

I'm using dhcpcd to delegate an IPv6 prefix for my local LAN.
It's receiving the prefix from the upstream router, which in this case
is an AVM FritzBox with IA_PD enabled.
Everything works great, except for one problem: The prefix is dynamic
and changes at least once a day. Dhcpcd does not react to that, so as a
result my LAN is unable to communicate via IPv6, as the prefix it still
has is no longer valid.

The Fritzbox seems to send some event on prefix change though, i have
the following in my log:

dhcpcd[2319]: enp2s0: unauthenticated RECONFIURE6 from fe80::....

But nothing happens after that.

The relevant part of my dhcpcd config is:

noipv6rs
noipv4ll
denyinterfaces enp1s0

interface enp2s0
ia_pd 1 br0/1/64


I'm using dhcpcd version 6.4.3
