QuoteThis memo describes a technique to dynamically discover the PMTU of apath. The basic idea is that a source node initially assumes thatthe PMTU of a path is the (known) MTU of the first hop in the path.If any of the packets sent on that path are too large to be forwardedby some node along the path, that node will discard them and returnICMPv6 Packet Too Big messages [ICMPv6]. Upon receipt of such amessage, the source node reduces its assumed PMTU for the path basedon the MTU of the constricting hop as reported in the Packet Too Bigmessage.
