Technical principle:
OSPD Open Shortest Path priority protocol. is one of the most widely used routing protocols in the current network. belongs to the internal network routing protocol. Being able to adapt to network environments of all sizes is a typical link-state protocol. The OSPF routing protocol spreads the link state information of the device to the whole network, so that each device in the net finally synchronizes a database with the whole network link state, then the router uses the SPF algorithm. The shortest path to the network is calculated as the root, which eventually forms the information of the whole Internet.
Experimental steps:
1. Divide the Vlan10 and Vlan20 on the three-layer switch in this experiment, where VLAN10 is used to connect the host and Vlan20 is used to connect R1.
2. Between the routers through the V35 cable through the serial port connection, the DCE end is connected on the R1, configures its clock frequency 64000.
3. The host and the switch through the direct connection, the host and the router through the intersection line connects.
4. Configure the OSPF routing protocol on the S3560.
5. Configure the OSPF routing protocol on the router R1, R2
6. Set the PC1, PC2 host default gateway to the IP address of the direct-attached network device interface
7. Verify that the PC1, PC2 hosts can pass through each other
