Exercise 1. Consider a datagram network using 32-bits host addresses. Su numbered from 0 to 3, and packets are to be forwarded to the link interfaces as follows ppose a router has four link, Destination Address Range 01100000 00001000 00000000 0000000 through Link Interface 01100001 00000000 00000000 0000000 through 01100001 00000001 00000000 0000000 through otherwise Answer the following questions (a) Rewrite the forwarding table using the a.b.c.d/r notatioin (b) Which link the router will choose to send the following packets with the following destination IP addresses? Show the process (1) 96.22.109.129/32 (2) 96.73.146.126/32 (3) 97.17.136.85/32 (c) Now assume that this router updated its forwarding table so that packets that have destination ad will be served to link 1. Show the new forwarding table using the a.b.c.d/z notation (d) Which link will the packets mentioned in problem (b) be forwarded to
