IPv6 , equivalent of net.ipv6.conf.all.accept_ra_from_local = 0 in NetworkManager?

[Thomas Schäfer <tschaefer t-online de>]

Hi,

I am playing a little bit with NAT64 and the public DNS64-Service by google.

My setup is an additionally raspi within the LAN.

The raspi itself uses the NetworkManager for getting its addresses.

[connection]
id=LAN
uuid=d7112198-4931-43a4-9e03-c18872b20668
type=ethernet
permissions=
secondaries=
timestamp=1463729812

[ethernet]
mac-address=B8:27:EB:B6:F2:93
mac-address-blacklist=

[ipv4]
dns-search=
method=auto

[ipv6]
dns-search=
ip6-privacy=0
method=auto

On the raspi runs a radvd for advertiseing the route 64:ff9b::/96 and tayga  
for NAT64 of course.

It works. But I have some small problems. One of them is. The raspi should not 
learn the route from its own radvd-service.

The route should only be set to the nat64-device by tayga. 

At the moment I have to remove the 
ip -6 route del 64:ff9b::/96 via fe80::ba27:ebff:feb6:f293 dev eth0
regulary 

I saw something like this could help:

but it doesn't work or I expect an other behaviour. 

Can this reached by the Networkmanager?

Or should I remove all dynamic assignments?

Is there simple ip6table -rule for that purpose?

Allowing RA from the Router/Fritzbox but not allowing the own RA?
