1. Considering the following figure as a schematic view of some parts of a network. Also, assume that the datagram X of size 5,000 bytes has just arrived at router C with the destination IP of 116.24.123.32.

Module 7 Table

Destination Address	Link Interface
116.23.8.0/21	O1
116.24.96.0/19	O2
116.24.64.0/18	O3
otherwise	O1

a. Assuming that router C forwards X to router B and router B decides to forward the datagram toward router A, explain how X is is fragmented at router B before getting forwarded. Also, specify the length of each fragment assuming that IP header is 20 bytes long.
