Re: mech-v2: processing of non-ipv6 packets [Re: mech-v2-05pre]



Errata correction :
IMHO, i would NOT like to support Option 2 for the very simple reason that proto-41 is ONLY for transporting/carrying IPv6 packets over IPv4.

Hi fred, Jinmei & pekka,
The idea of suggesting the option 1 is to make it clear to the implementator
of possible bogus packets which needs to be taken care.
 
But definitely I am also not against option 3 provided that we add the info of "possible bogus packets threats" in the appropriate section in the draft.

If we can't reach agreement on new text with "MUSTs" then we should
revert to saying nothing at all and trust that robust implementations will
do the right thing w/o gratuitous specification, which I believe is also
reinforced by Brian's citations:

I agree that these points strongly suggest the silent discard, but wouldn't
that indicate solution 3? (BTW, "parsimonious" seems an odd word to
find in a document about simplicity.)
