The packet is forwarded to an IPv4 router that supports a Maximum Transmission Unit (MTU) of 400 bytes. Assume that the length of the IP header in all the outgoing fragments of this packet is 20 bytes. The fragmentation offset value stored in the third fragment is _______.

Best answer 4 votes 4 votes mtu = 400bytes, header = 20 bytes, data in one frame = 400 – 20 = 380 380 is not divisible by 8 but 376 is so the frame becomes 376-databytes and 20-header 376/8 = 47 fragment offset of 1st frame is 0, 2nd→ 47, 3→ 94 so answer is 94 manishi answered Dec 18, 2021 selected Dec 27, 2021 by LRU manishi comment Share Follow See all 0 reply Please log in or register to add a comment.
