MPLS over routed VLAN interfaces (RVIs) or Layer 3 subinterfaces

One can now use an RVI or a Layer 3 subinterface as the MPLS core-facing interface. The RVI functions as a logical router, eliminating the need for having both a switch and a router. Layer 3 subinterfaces allows to route traffic among multiple VLANs along a single trunk line that connects an EX Series switch to a Layer 2 switch.
