If only the configuration in FIG PC, routing switches, and wiring, routing discovery and communication line is not connected to the scale, because there is not important for the configuration.
Specific configuration is as follows:
1, host configuration
PC2 and PC4 in a LAN, the host position but nowhere IP, subnet mask, gateway with PC2
from other LAN PC3. Configured as follows
2. Router Configuration
Router (config-IF) #IN
Router (config-IF) #int
Router (config-IF) #int Fa0 / 0
Router (config-IF) # IP address 192.168.1.100 255.255.255.0 %% % + subnet mask gateway
Router (config-IF) # NO the shutdown
Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router (config-IF) #int
Router (config-IF) #int Fa0 /. 1
Router (config-IF) #ip address 192.168.2.100 255.255.255.0
Router (config-IF) #no the shutdown
according to the above operations are done!
