Routing TCP/IP, Volume 1 (2nd Edition)

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.

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

• RTC, the second entry, should be ip route 172.20.208.0 255.255.240.0 172.20.16.50 and fifth entry, should be ip route 172.20.80.0 255.255.240.0 172.20.20.1

The mistakes are as follows:

• RTC: The route to 10.5.8.0/24 points to the wrong next-hop address.

• RTC: The route to 10.1.1.0/24 should be 10.5.1.0/24. (There is no 10.1.1.0/24 in the network.)

• RTC: There is no route to 10.5.4.0/24.

• RTD: The route to 10.4.5.0/24 should be 10.5.4.0/24.
