Rookie must see: layer 3 switch to achieve VLAN interworking experiment (picture and text)

Small white must see: three-layer switch to achieve VLAN interoperability experiment (illustrated). experimental environment

Lab requires GNS3 and c2691 routers

II. Experiment 3. experimental procedure

First we set SW-2 up. First, we add vlan10 and vlan20, as shown in Figure 1.

Next, assign the interface to the corresponding vlan. Operation as shown below

We can also check the interface settings as shown below.

Next we set up R3. First, let's set up the IP address of R3. Operation as shown below.

Then we configure static routing for R3

Then we set up sw-3. Let's start by adding vlan10 and vlan 20 to sw-3.

We also need to set up trunk for SW-3's f1/0 interface, as shown in the figure

Next, we set up the gateway of sw-3 virtual interface, as shown in the figure

Open the Layer 3 interface, close the switch interface, and then set the IP address of the physical interface. Fig.

Since sw-3 has only one route to other routers, it is assigned a default route. Operation is as shown in the figure.

Then we should set ip for pc. Operation as shown below.

The experiment is over for now. Finally, you only need to take PC1 to ping PC2 and PC3 on the line, ping successful experiment is successful.
