Suppose that host A is connected to a router R1, R1 is connected to another router R2, and R2 is connected to host B. Suppose that a payload (i.e., data + TCP header) of 1200 byes is passed to the IP layer at host A for delivery to host B. Assume that the size of IP header is 20 bytes. Assume that the MTU at the link between host A and R1 is 800 bytes, the MTU at the link between R1 and R2 is 512 bytes, and the MTU at the link between R2 and host B is 1024 bytes. Show the total length, MF, Fragment offset fields of the IP header in the three packets transmitted over the link between R2 and B.

Note that only an integer number is allowed in each of the following blanks.

First Packet: Total length (first blank), MF (second blank), Fragment offset (third blank):

Second Packet: Total length (first blank), MF (second blank), Fragment offset (third blank):

Third packet: Total length (first blank), MF (second blank), Fragment offset (third blank):
