Overlapped VLANs

Question

Hi everyone,

I'm completely new here and I'm happy to be with all of you.

So I have a pc6248 and I want to make use of it. Here are what I did on the switch:

Created 3 vlans: 10, 20, 30.

vlan 10,20,30

Set vlans interface IP addreses:

ip address 192.168.10.1 /24 [for vlan 10]
ip address 192.168.20.1 /24 [for vlan 20]
ip address 192.168.30.1 /24 [for vlan 30]

Added ports to the vlans:

interface range ethernet 1/g1-1/g3
switchport mode access
switchport access vlan 10

interface range ethernet 1/g4-1/g6
switchport mode access
switchport access vlan 20

interface range ethernet 1/g7-1/g9
switchport mode access
switchport access vlan 30

PC1 connected to vlan 10: 192.168.10.11 /24
PC2 connected to vlan 10: 192.168.10.22 /24
PC3 connected to vlan 10: 192.168.10.33 /24

PC4 connected to vlan 20: 192.168.20.44 /24
PC5 connected to vlan 20: 192.168.20.55 /24
PC6 connected to vlan 20: 192.168.20.66 /24

PC7 connected to vlan 30: 192.168.30.77 /24
PC8 connected to vlan 30: 192.168.30.88 /24
PC9 connected to vlan 30: 192.168.30.99 /24

So far so good. A PC can ping other PCs in the same vlan but not other PCs in other vlans.

But I need more than that, such as, PC1 (vlan 10) and PC4 (vlan 20) and PC7 (vlan 30) can ping each other.

I heard of routing but I don't know how to do it.

Thanks for any help.

Thank you DELL-DANIEL, ip routing really makes a PC in one vlan seeing other PCs in other vlans but I just want some specific PCs in one vlan to see some specific PCs in other vlans.

In my example, PC1 (vlan 10), PC4 (vlan 20) and PC7 (vlan 30) can see each other and that's good but I also want PC2, PC3 (vlan 10) can not see PC4 (vlan 20) or PC7 (vlan 30).

How do I do it?

Thank you DELL-DANIEL for pointing the direction. It seems a very long road to go. I'll try anyway. Thanks again.
