-----------------------------------------------

Prefix Match                          Interface

-----------------------------------------------

1

0

11

1

111

2

Otherwise

3

-----------------------------------------------

For each of the following 5 host addresses, give the matched interface # using above forwarding table. (10 points)

10100000 10111111

11110000 10111111

11010000 10111111

01110000 10111111

11000000 10111111

Solution

Answer

Destination Address Range Link Interface

10100000 10111111 0

11110000 10111111 2

11010000 10111111 1

01110000 10111111 3
