[AusNOG] Fwd: Life in the trenches of large-ish IPv6 networks

[Jonathan Thorpe]

This is actually a bit more than a firmware bug.

While software could have a role to play in this particular case, the firmware failure is more of a symptom of a wider problem with the way addresses are discovered and assigned in stateless IPv6 configurations.

It seems applying an IPv4 understanding of IP to MAC resolution to IPv6 (which uses multicast instead of broadcast) is an easy thing to do when it's designed to achieve the same outcome, however resulted in major problems in this case.

I thought it was quite interesting.
