Erik,
My understanding of RFC 3168 is that when the tunnel interface
forwards an IPv6 packet to an IPv4 interface with an ECT(0) or ECT(1)
codepoint in the traffic class field, it MAY set the codepoint to CE if
congestion is experienced. I interpret the MAY to mean that the other
option is to drop the packet. If the packet is to be dropped, should it
be dropped silently? Also, could a link restriction be considered as
congestion? If so, does drop silent also entail NOT sending an
ICMPv6 "packet too big" message back to the source?
Thanks - Fred
