One of the easy and most accurate ways to test for optimum MTU is to do a simple DO S P ing test. You will simply send out ping requests and progressively lower your packet size until the packet no longer needs to be fragmented. draft-ietf-6man-mtu-option-02 - IPv6 Minimum Path MTU Hop draft-ietf-6man-mtu-option-02 Abstract This document specifies a new Hop-by-Hop IPv6 option that is used to record the minimum Path MTU along the forward path between a source host to a destination host.
