You are creating the “perceived” security problem yourself, by requiring processing deeper into the packet than is required. Just comply with RFC8200. As long as a router is not configured to process any HBH options, it can ignore the header. You seem to think HBH still means “punt to software”. If it ever meant that. There’s no need for rate-limiting for not processing HBH obviously. Cheers, Ole
