Hey guys i made a topology for a Network carrying voice traffic BUT i cant get any connectivity. I have uploaded the topology here! Do i need to configure intervlan routing on each router or only on one?
i also want to make the switch 1 and switch 5 have a VPN tunnel to switch 3 if that makes sense! How would i do that guys and still have my vlans work? In the near future i want to also configure voice vlans so i need all of this to work simulateously! sorry for my noob questions guys but i really need some help, have been scratching my head for awhile now.

To make the routing work between the vlans you need to define the connection between router 2 and switch 5 as a trunk on the switch and put sub interfaces on router 2 with the proper tags. You would need static routes or run a routing protocol to make the traffic flow between the routers. You also need to define all the networks between the routers and to the other 2 pc which is pretty straight forward.

I suspect a vpn tunnel between switch 3 and switch 5 is way beyond you skill level and I not 100% sure it is supported in any of the simulators. But if you example you wanted PC 2 to actually be on the same vlan as softphone 3 you would have to extend a layer 2 vlan over a layer 3 network. This is either done with MPLS which I...

This is either done with MPLS which I won't even attempt to explain how to configure. Or you can use L2TPv3. This pretty much is a dumb tunnel that takes layer 2 packets in one end wraps a layer 3 header on them and dumps them out the other. It puts a huge burden on the router since it must fragment and reassemble packet. The command you can try to see if works in the simulator is XCONNECT in the interface config mode on a router. The switches are stupid the don't even support gre tunnels.
