Question #02 [CLO: C3] [Marks: 10] a) Keep in mind the concept of IP datagram fragmentation. Suppose there is a datagram of 8000 bytes and this datagram needs to be routed on a link with MTU of 1800 bytes. Original datagram is stamped with an ID #X. Perform data fragmentation. (5) b) Write the reason of using NAT table in a network? Suppose in private network ID is 172.16.0.0 and the public IP is 140.56.17.1. Write NAT table if private network IP sends data to a destination (write destination address& port number of your choice). (3) c) What is the problem of oscillations in Link state routing algorithms and what is the reason of this? (2)
