Build a network, the left LAN is 10.0.0.0 network segment, right LAN is 12.0.0.0 network segment, the middle is WAN 11.0.0.0 network segment

The above success, but not very familiar with, the following again

1. First create a network with a visual interface

2. It seems that the computer must first connect with the switch to connect with the router

3. The rest is very simple, configure the static route is OK

4. The key is that when you ping12 the network segment from the 10 segment, you will not be able to reach it, just because the router can automatically forward the data to the neighboring network segment of the router, but the 12 and 10 segments are not adjacent, ROUTE0 don't know how to forward the data to the 12 segment

5. You need our administrator to manually enter the routing table

6. Next is the configuration of the ROUTE0

// Add route table router>enablerouter#config t//  tell ROUTE0 if you want to send a message to the 12.0.0.0 network segment (This segment mask is 255.255.0.0)/ /  Send the message to the 11.0.0.2 port to 12.0. 0.0 255.255. 0.0 11.0. 0.2

7. Follow the above actions to continue configuring ROUTE1

8. This time after the host PC0 Ping PC4 can be successful
