Configure MPLS VPN on Ethernet VLAN interfaces

I created Ethernet subinterfaces with VLAN and isl/dot1q
encapsulation.
then i tried Applying VRF (part of MPLS VPN) to it, and it worked
without giving error.
But I believe, VPN isnt supported on VLAN interfaces.. it doesnt make
sense to have L3 tunneling inside L2.
I dont know if this configuration works in real, but it is accpeted by
cisco CLI.

Any ideas?

what you probably have is each vlan can be bound as an interface to a
VRF.

what you have is vlans which are logical interfaces to the different
emulated routers in each VRF.

FWIW the way we support multiple VPNs to a site with Ethernet WAN
access is to extend each VRF from PE to CE as a different VLAN tag

it does work. it does not need VPNs or MPLS to be useful.

for example we run management in 1 VRF in a L3 switch, and customer
traffic in another.
2 logical routing instances in different VRFs, with different routing
tables.
