What is Path MTU Discovery?
What will be an ideal response?
Path MTU Discovery (PMTU) is a newer technology (2007) created to determine the best MTU settings between two networks (such as a LAN and a WAN through an ISP) and fix mismatches between them. It essentially adds a "Don't Fragment Flag" to an IP packet, and pings another device to test the MTU settings. It can automatically correct the MTU size on the sending device if there is a mismatch.
