Howdy,
  This question is kind of off the wall but curiosity is kicking in here. Is it possible on a Cisco c3750 switch or any higher switch to create a tunnel between two vlans say vlan 20 to vlan 40? I know you can create Tunnels between routers. I was just wondering if it's possible to create that virtual connection between two vlans.

Hope this makes sense..

I am presuming that the VLANs are on two separate locales, as tunneling between two VLANs at the one location would be mundane.

Usually you'd just create a GRE tunnel between routes and setup routing for the relevant VLANs and sites, however you are referring to a Layer2 tunnel: http://www.cisco.com/en/US/tech/tk364/technologies_configuration_example09186a00801f66fa.shtml

Iif you just want to bridge the VLANs.. I.E. make them as one:

On one switch:

int Fa0/1
 switchport access vlan 20
 switchport trunk encapsulation dot1q
 switchport mode access

Other switch:

int Fa0/2
 switchport access vlan 40
 switchport trunk encapsulation dot1q
 switchport mode access

Plug the ports together.

Voila, kinda defies the point of having VLANs though...
