vlan2 switch 2950
vlan3 switch 2950
vlan4 switch 2960 connecting trunk all vlan connecting server

Hi ,
To have inter-vlan communication you need to have L3 network gear in your network (L3 Switch/Router)

Hi,

concern is that I want my vlan not contacted them and I have only one réeau gold there is I can ping the all or none I tag the port without much success of the truck is activated nothing works.
I test packet trace before the start of production.

Hi ,
For all 3 VLAN , Gateway IP address must be configured on L3 Switches . I dont see any ip address configured on VLAN router . Kindly configure it .
vlan router#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/1 unassigned YES unset up up
FastEthernet0/2 unassigned YES unset up up
FastEthernet0/3 unassigned YES unset up up
FastEthernet0/4 unassigned YES unset up up

Hi ,
You Cant use Same network across multiple Vlan .You need to use different subnet
VLAN10
10.20.10.1 switch1 IP
10.20.10.10 Server IP
VLAN20
10.20.20.1 switch1 IP
10.20.20.10 Server IP
VLAN30
10.20.30.1 switch1 IP
10.20.30.10 Server IP
If you want to isolated host within same network you need to use private vlan .

Hi,
thank you very much for all these explanations
in my case I have a server pool must tell all my vlan and I wanted to create SEVERAL vlan one per floor of the building 1,3,5:
VLAN10 = 1st floor
vlan20 + server pool floor = 5
vlan30 = 3rd floor
the vlan 20 would be the primary vlan 10 and 30 isolate?
my approach is the right one?
thank you for your temperature and your response
