[RFC 4861] upper-layer reachability confirmation

[Yukiyo Akisada <akisada at tahi.org>]

Hi, all.

I have a question about upper-layer reachability confirmation defined in RFC 4861.

When the neighbor cache state for the default router is STALE
and the host sends a packet to off-link,
the default router sends redirect packet to the host.

Can the host considers that the default router is REACHABLE?

Personally, I didn't expected this behavior.
But I found that an implementation behaves like this
when I'm developping the conformance tester.

How do you think about this behavior?

Thanks,
