Hi Brian,
In any case if we see this entire thread the only technical concern with EH
insertion was MTU. And how that issue is solved when you do additional IPv6
header encap ?
PMTUD applies to the path between source A (encapsulator) and destination B
(decapsulator). If you decapsulate at B and the encapsulate again, PMTUD
applies to the path between B (encapsulator) and C (decapsulator). They are
completely independent; it's a new packet. PMTUD doesn't occur between A
and C at all.
Are you saying that it is "legal" to fragment IPv6 packet by a router at the
encapsulation point in the network ?
That would be news to me.
Yes. It is legal. Please take a look at section 7 of RFC2473.
