Experimental tasks:
-

-
For dynamic routing RIP and OSPF experiments, establish a topology pc1>>R1>>R2>>R3>>pc2, so that pc1 and pc2 can communicate with each other, and configure the silent interface on the PC side.

Multi-layer switch SVI configuration experiment, establish VLAN10>>Switch SW>>VLAN20, so that the two VLANs can communicate with each other,
-
Set up inter-vlan routing for each department in the company network of the previous experiment, so that each department can communicate
The main technologies used in this experiment are: the configuration of dynamic routing protocols rip and ospf and the mutual introduction between the two, the single-arm routing and the svi port of the three-layer switch to realize the communication between VLANs. The following is my experimental configuration idea , for your reference only, if you think it is good, you may wish to like + follow, thank you
A dynamic routing RIP, OSPF experiment, establish a topology pc1>>R1>>R2>>R3>>pc2, so that pc1 and pc2 can communicate with each other, and configure the PC terminal silent interface.
1.1 Experimental Analysis
This experiment mainly investigates the routing protocol configuration and bidirectional import of rip and ospf. As shown in the figure below, rip is configured on the left and ospf is configured on the right. On the handover router R2 between rip and ospf, bidirectional import is performed, that is, rip is introduced in ospf, and Introduce ospf in rip, so as to realize the intercommunication of the whole network.

Check the routing table with dis ip rou on R1, and find that the route of the network segment in the ospf area has been learned through rip

2 Familiar with configuring inter-vlan routing technology: multi-layer switch virtual interface SVI and single-arm routing
2.1 Experimental Analysis
One-arm routing refers to the way of configuring sub-interfaces (or “logical interfaces”, there is no real physical interface) on an interface of the router to realize the interconnection between different VLANs (virtual local area networks) that were originally isolated from each other.
One-arm routing realizes communication between different VLANs. The sub-interface of the one-arm router is used as the gateway of the PC. Remember to enable the arp broadcast function after the sub-interface is established.

Three-layer switch SVI configuration experiment, establish VLAN10>>switch SW>>VLAN20, so that the two VLANs can communicate with each other
3.1 Experimental Analysis
The virtual interface svi of the three-layer switch is used as the gateway of the PC, and it can also realize the communication of different VLANs. This is also a technology often used in production. The VLANIF interface is based on the interface of the network layer and can be configured with an IP address. With the help of the VLANIF interface, the layer-3 switch can realize the routing and forwarding function. I often understand the layer-3 switch as a router
