WebDec 1, 2024 · Encapsulation The data payload section of an Ethernet frame is exactly what the IP datagram is, and this process is known as encapsulation. The entire contents of an IP datagram are encapsulated as the payload of an Ethernet frame. Additionally, our IP datagram also has a payload section. WebFragmentation and Reassembly Using an encapsulation (IPv4-in-IPv6 or anything else) to carry IPv4 traffic over IPv6 will reduce the effective MTU of the datagram.
