> As for details into the v6LC_2_3_6_G test failure:

> The log shows the test fails due to processing an invalid redirect packet
> (ie: it's a negative test). The redirect packet contains a multicast
> address as a target address. RFC2461 (p.26) doesn't explicitly state this
> is invalid:
>
> Target Address
> An IP address that is a better first hop to use for
> the ICMP Destination Address. When the target is
> the actual endpoint of communication, i.e., the
> destination is a neighbor, the Target Address field
> MUST contain the same value as the ICMP Destination
> Address field. Otherwise the target is a better
> first-hop router and the Target Address MUST be the
> router's link-local address so that hosts can
> uniquely identify routers.

> But the test does appear to make sense based on the last sentence. The
> linux kernel I'm testing shows an echo response trying to use the
> multicast address from the redirect packet as it's first hop. This is
> what causes the test to fail. The expectation is that the linux kernel
> would ignore the redirect packet entirely.

> As stated, this is the ONLY test in the whole Phase2 test suite that
> fails. I understand the failure, but I don't understand how the 2.6.20
> kernel is Phase2 certified. At least not with the current Self_Test test
> suite.
