2 192.168.13.175/28 is the broadcast address of subnet 192.168.13.160/28.

Chapter 3

1 Subnet 192.168.1.64/27 will no longer be reachable from Piglet. Subnets 10.4.6.0/24 and 10.4.7.0/24 are also no longer reachable from Piglet.

2 Mistakes occur in the following:

• RTA, the second entry, should be ip route 172.20.80.0 255.255.240.0 172.20.20.1

• RTB, the third entry, should be ip route 172.20.208.0 255.255.240.0 172.20.16.50
