- the processing of HbH would kill the Internet of course (at least with most routers), should HbH be separately called?
I think that'd be sensible. -- and seem to recall that there was some I-D (RFC?) focusing on HbH? (or was it on router alert option?)
You're probably thinking of draft-baker-6man-hbh-header-handling, but there's a slight conflict between that and RFC 7045, which made a normative change to HbH by downgrading them to SHOULD: The IPv6 Hop-by-Hop Options header SHOULD be processed by intermediate forwarding nodes as described in [RFC2460]. However, it is to be expected that high-performance routers will either ignore it or assign packets containing it to a slow processing path. Designers planning to use a hop-by-hop option need to be aware of this likely behaviour. Also of course the next version of 2460bis will revisit this topic. Brian
