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.

1. (20 points) Assuming that router C forwards X to router B and the following table summarizes the forwarding table of router B, at which link interface, X (or its fragments) is (are) forwarded by router B? Why?

Module 7 Table

116.23.8.0/21	O1
116.24.96.0/19	O2
116.24.64.0/18	O3
otherwise	O1
