Purpose: understand the inter-domain routing configuration and the basic principles of command
Subjects: four routers, two hosts
Experimental Procedure:
1. The equipment needed to drag topology area,
Configure the router disk 128M, you need to add three interfaces interface
2. connection, open interface information, set the interface IP environment
3. Click Run to start configuring PC
R1 interface IP configuration
R2's IP
R3 of IP
R4's IP
After 4.IP configuration is complete, the next step is to begin OSPF configuration, configure loopback, router-id, where the network itself declared position
R2 configuration, and now has full configuration of the
R3 Configuration
R4 configuration
5. Check each router among the routing table
R1:
R2:
R3:
6. Pay attention, I have to add drama, and this time found R3 routing table only five segments, not 10, and 11 segments, this time again to go back to troubleshoot
R1 routing table is complete, so the R1 is right
For investigation from the beginning, I have better luck, directly found in the set of experimental data, 192.168.11.0 network has an interface with the wrong, just or R3, and this time we should pay close attention to changes,
After modifying the topology in FIG, R3 have need to modify the interface information, segment redeclaration
After the announcement, after a while there will be a reaction, then check the routing table
Complete the
R4：
No problem
8.PC1 go pingPC2
9. Perfect
