hello,
ok i made a mistake in my previous mail. Actually, pmtu discovery fails if:
1. there is a link in the ipv6 internet which has mtu < 1280 (which
shouldn't be possible anyway).
2. if there is a link in the ipv4 side across the translator which has mtu <
1280.
So, now my re-framed question is :
Do I need to add the frag header to every packet when the pmtu fails??
PS: ignore all the other stuff in previous mail:)
regards,
imran
