Folks,
RFC 2460 states that every link in an internet have an MTU of 1280
octets or greater, and that any link that cannot convey a 1280-octet
packet in one piece must provide fragmentation and reassembly at a
layer bellow IPv6.
However, while talking about the specs with a few folks (who
preferred to remain anonymous), it was mentioned to me that in a
number of scenarios (not necessarily those that involve tunnels),
some links have an MTU smaller than 1280, and they do not perform the
"fragmentation and reassembly function at a layer bellow IP" that RFC
2460 requires.
Any operational data or experiences with those link technologies will
be more than welcome.... either on- or off-list.
Thanks!
Kind regards,
