Ok, now I oriented myself: shouldn't the function not just bail out after this line?

https://github.com/RIOT-OS/RIOT/blob/62308d200c4a2d61a5b9a7cdc8ee59785640ea20/sys/net/gnrc/network_layer/ipv6/nib/nib.c#L696

I have to reread RFC4861 to be sure, but from what I can see, everything after is just config and taking config from a "dying" router does not seem to be wise. The only thing I am not sure about is the handling of the SLLAO option, as it could have implications for neighbor unreachability detection (for a "dying" router we might want to have it be detected as unreachable ad one point ;-)).
