Answer:
Explanation:
Given, total payload is: 2000 bytes
MTU is: 1500 bytes
Header is: 20 bytes
Base header is: 40 bytes
Total number of fragments = Total Payload / MTU
= 2500 / 1500
= 2 fragments
Fragment Base header Fragmentation header Authentication
header + Data
1 40 bytes 8 bytes 20 bytes +772bytes
2 40 bytes 8 bytes 792 bytes
