Two questions:

1) How did you run fake_router6?
2) Could you share the packet trace (decoded (in the body of an email),
or either post the URL of a pcap file) -- This is to answer these questions:
 a) is the tool advertising many prefixes in the same RA? Just sending
multiple RAs? Something else?
 b) What's the difference between the packets accepted by Linux, and the
ones ignored by Linux?

Thanks!

Best regards,
