Purpose: PC9 and PC10 are interconnected.

Analysis: it can be seen from the figure that there are two routers connected between pc9 and pc10. In order to achieve the purpose of the experiment, the core problem is to configure the IP address of the two ports of router R1, and then configure the static route. The specific commands are as follows:

1 manually configure IP addresses 192.168.1.1 and 192.168.1.2 for pc9 and pc10, and manually configure gateway 192.168.1.254, respectively

And 192.168.2.254.

2 configure the router

(1) configure R1

Router > enable / / enter privileged mode

Router#configure terminal / / enter privileged mode

Router (config) # hostname R1 / / modify the router name

R1 (config) # interface gig0/0 / / enter interface gig0/0

R1 (config-if) # no shut / / enable interface gig0/0

R1 (config-if) # ip address192.168.1.254 255.255.255.0 / / configure this interface gateway

R1 (config-if) # exit

Enter gig0/1 in configuration mode and configure the gateway to 192.168.20.1 according to the above command

Configure a static IP address:

R1 (config) # ip route 192.168.2.0 255.255.255.0 gig0/1

Analysis: add a static route to the network segment 192.168.2.0 on the port gig0/1 of router R1

Another command to configure a static IP address:

R1 (config) # ip route 192.168.2.0 255.255.255.0 192.168.20.2

Parse; access the network segment 192.168.2.0 / 24 through the R2 port with the IP address 192.168.20.2

The two commands have the same effect.

Successfully configured verification command: R1 verify show ip route / / View the routing table

At this point, R1 has been configured, and R2 has been configured with the same command. Configuration is complete, enter the command ping 192.168.2.1 in pc9, and you can communicate with ping. The purpose of the experiment is achieved.

Summary: 1 Gateway corresponds to a port, not a device

2 the device where the gateway is located must have the function of a router

3 Gateways are needed only when different network segments communicate

4 when configuring static routes with R1 (config) # ip route 192.168.2.0 255.255.255.0 192.168.20.2, the IP address of the peer device is used.
