pppoe-log - Growing "Protocol-reject" entries after move to new Telekom platform

Hi,

today I was moved to the new platform (BNG preparation) of the german provider Telekom.

Since the switchover, I'm periodically getting these kind of entries in the ppp_pppoe0.log:

The only difference I see from the provider side is that the new platform assigns me also an IPv6 subnet beside my fixed IPv4 address (here is a paste from the customer control panel):

Ihre Internetverbindung wird immer mit diesen IP-Adressen aufgebaut.
Sie können bei Bedarf zu den IP-Adressen einen Reverse DNS-Eintrag vornehmen.
IPv4:
xx.xxx.xxx.xxx
IPv6 (Öffentlich/WAN):
2003:000a:xxxx:xxxx:0000:0000:0000:0000/64
	
IPv6 (Kundennetz/LAN):
2003:000a:xxxx:xxxx:0000:0000:0000:0000/56

Could it be that the available IPv6 subnet is responsible for the growing error messages in the log?

Any idea how I can get rid of these errors? Apart from the error messages the PPPoE works fine (I'm just using IPv4 with a fixed address)
