In your previous mail you wrote:
I think what Francis means is that all nodes should know how to process the
routing header. That is, they know the header type and they layout of
the header.
=> exactly. Your previous mail is a more accurate (than mine) description
of what should be the policy for a host implementation.
Some implementations took a really simplistic approach and process
routing header every time including forwarding. This is what started the
whole thread. Other implementations took a safer approach an decided that
processing or forwarding is not appropriate under some circumstances
(like when the node is configured as a host).
=> safer is better!
So as you can see, this whole thread simply a different interpretation of
the specs. It would nice if this issue would be clarified in some
document, but I can live without it.
=> this is a policy issue so we can understand why the current specs
say nothing about it. But I disagree about different interpretation,
in fact there is nothing to interpret (:-)! The IPv6 host requirement
document should fill the gap, if the issue becomes critical we can
write and adopt a specific document (which will be included in host
requirement). I don't know if there is an emergency?
