I have a OSPF topology with three areas and the backbone area.
On few routers of each area I have connected a set of switches running VTP ans RSTP.
So well, what I want to do is share a VLAN on all the switches of the OSPF topology, for instance VLAN 30.
I haven't tried yet because I've done just InterVlan routing by using a Router with SubInterfaces, only sharing the VTP data and Vlan information on the switches connected to that Router, now I'm trying to pass that information to other routers connected to the router that Vlan Manager Router.
Thanks in advance.

VTP is layer-2, and can't pass through the routers. Your OSPF boundary is the OSPF areas you already have defined and you can't pass vlan 30 to all the routers.

That was my fear, but I hoped a way to pass from L2 to L3 and because I can utilize a router to comunicate different VLAN and I thought I could be able to "Encapsulate" the L2 VTP Administrative Frames to L3 Packets, but that is just a dream!
Thank's for your reply Reza.

You can tunnel VTP using QnQ.
