1. Consider a datagram network using 32-bit host addresses. Suppose a router has four links, numbered 0 through 3, and packets are to be forwarded to the link interfaces as follows:

Prefix Match	Link Interface
11100000 000	0
11100000 00100000	1
11100000 0011	2
11100000 00110001 10	2
Otherwise	3

Describe how your forwarding table determines the appropriate link interface for datagrams with destination addresses:

a) 11000000 00110001 01010001 01010101

b) 11100001 00100000 00010001 01110111
