Maximum Transmission Unit. In Internet Protocol version 6 (IPv6), all networks must support a packet of at least 1280 octets. The recommendation, however, is that all networks be configured to support an MTU of 1500 octets or greater in order to support encapsulation of Ethernet payloads without incurring fragmentation. See also encapsulate, Ethernet, fragmentation, IPv6, octet, packet, and payload.
