Fragmentation
The Branch Gateway supports IP fragmentation and reassembly. The Branch Gateway router
can fragment and reassemble IP packets according to RFC 791. This feature allows the router
to send and receive large IP packets where the underlying data link protocol constrains the
Maximum Transport Unit (MTU).
IP fragmentation involves breaking a datagram into a number of pieces that can be
reassembled later. The IP source, destination, identification, total length, and fragment offset
fields, along with the more fragment and don’t fragment flags in the IP header, are used for IP
fragmentation and reassembly.
IP fragmentation works as follows:
• Each IP packet is divided into fragments
• Each fragment becomes its own IP packet
• Each packet has same identifier, source, and destination address
