[6bone] why there is no checksum in IPv6 header?

[navaneetham]

I got your point stewart. the reason why IPv4 has header checksum is, there
may be a situation layer 2 may not have checksum (am I right?). did the same
situation never happen or what in IPv6? how to handle this?


Thanks&Regards,
Navaneetham

Speed. You likely do a checksum at layer 2 and layer 4, so why do
another. If the header is corrupted, the packet is dropped. Most books
explain this rationale.
