VLAN not spreading on GNS3
I'm having trouble with this lab. I created a VLAN on DW2 and the VLAN is not spreading to the other switches. I can ping DW2 to and from, but the switch is not spreading. I have DW1 and DW2 as a Servers and with a POD1 domain, and I have ASW1 and ASW2 as clients with a POD1 domain. I think this is a bug on GNS3

I don't think you are running into a bug, I've set up VTP on dynamips a few times and everything worked as it should.
How are you adding the new VLAN? A show vlan-s should let you know if its being added to the database properly.An expert is a man who has made all the mistakes which can be made. -

I created a VLAN 11 on DW1 and VLAN 11 spreaded to all switches, but not to DW2. I do sh vlan and ASW1 and ASW2 have VLAN 11, but VLAN 12 that I created on DW2 is only on DW2. -

You don't have any interface configured as trunk on DW2 switch. VTP only flows on trunk ports. So configure DW1-DW2 port as trunk on DW2. If VLAN even than spread than it should be issue with VTP domain or password on DW2. Do have a look at that.
Do share the output of VTP on DW1 and DW2, for us to have a look. -

Thanks, I swear taht I config the inter with the switch mde trunk, but I guess I didn't. ThanksYou don't have any interface configured as trunk on DW2 switch. VTP only flows on trunk ports.
