Routing TCP[s]IP (Vol. 11998)

In the internetwork of Figure 3.3 and the associated configurations, the route entries for Piglet are changed from

Piglet(config)# ip route 192.168.1.0 255.255.255.0 192.168.1.193 Piglet(config)# ip route 10.4.0.0 255.255.0.0 192.168.1.193

to

Piglet(config)# ip route 192.168.1.0 255.255.255.224 192.168.1.193 Piglet(config)# ip route 10.0.0.0 255.255.0.0 192.168.1.193

What is the result?

The static route configurations for the routers in Figure 3.27 are as follows :

RTA ip route 172.20.96.0 255.255.240.0 172.20.20.1 ip route 172.20.82.0 255.255.240.0 172.20.20.1 ip route 172.20.64.0 255.255.240.0 172.20.20.1 ip route 172.20.160.0 255.255.240.0 172.20.30.255 ip route 172.20.144.0 255.255.240.0 172.20.30.255 ip route 172.20.128.0 255.255.240.0 172.20.30.255 RTB ip route 172.20.192.0 255.255.240.0 172.20.16.50 ip route 172.20.224.0 255.255.240.0 172.20.16.50 ip route 172.20.128.0 255.255.240.0 172.20.16.50 ip route 172.20.160.0 255.255.240.0 172.20.30.255 ip route 172.20.144.0 255.255.240.0 172.20.30.255 ip route 172.20.128.0 255.255.240.0 172.20.30.255 RTC ip route 172.20.192.0 255.255.240.0 172.20.16.50 ip route 172.20.208.0 255.255.255.0 172.20.16.50 ip route 172.20.224.0 255.255.240.0 172.20.16.50 ip route 172.20.96.0 255.255.240.0 172.20.20.1 ip route 172.20.82.0 255.255.240.0 172.20.20.1 ip route 172.20.64.0 255.255.240.0 172.20.20.1
