First connect the topology of the network

Then, set the ip address of PCs
PC1 IP![]() | PC2 IP![]() |
|---|---|
PC3 IP![]() | PC4 IP![]() |
Set gatway of PC1 and PC2 as the ip address of the router1192.168.1.1

Set gatway of PC3 and PC 4 as the ip address of router2 192.168.3.1

Set the router 1 and router 2 interface ip address as
Router 1 Interface 0 ![]() | Router 2 Interface 0 ![]() |
|---|---|
Router 1 Interface 1 ![]() | Router 2 Interface 1 ![]() |
enable the router, and set the static routing as:
| Router 1 | Router 2 |
|---|---|
![]() | ![]() |
ping the other PCs and check the connection.
![]() | ![]() |
|---|---|
![]() | ![]() |
First connect the network like this:

Then, set the interface ip for PCs:
PC1![]() | PC2![]() |
|---|---|
PC3![]() | PC3![]() |
PC5![]() |
| Device | IP | VLAN |
|---|---|---|
| PC1 | 192.12.10.11 | 10 |
| PC2 | 192.12.10.12 | 10 |
| PC3 | 192.12.20.13 | 20 |
| PC4 | 192.12.10.14 | 10 |
| PC5 | 192.12.20.15 | 20 |
Then, add the VLANs 10:VLAN-10 and 20:VLAN-20 in all three switches

| Switch 1 to PC1 | Switch 1 to PC2 | Switch 1 to PC3 | Switch 1 to Switch 2 |
|---|---|---|---|
![]() | ![]() | ![]() | ![]() |
| Switch 3 to Switch 1 | Switch 3 to Switch 2 |
|---|---|
![]() | ![]() |
| Switch 2 to PC4 | Switch 2 to PC5 | Switch 2 to Switch 2 |
|---|---|---|
![]() | ![]() | ![]() |
Finally, check the connectivity:
![]() | ![]() |
|---|---|
![]() | ![]() |
![]() |
In conclusion, the VLAN has a isolation effect.
| PC1 | PC2 | PC3 | PC4 | PC5 | |
