However, with the emergence of the Multi-Protocol Label Switching (MPLS) technology, the debate has once more surfaced.Layer 3 and Layer 2 VPN Characteristics. There are two fundamentally different kinds of Layer 2 VPN service that a service provider could offer.
In a layer 2 VPN, L2 frames (usually Ethernet) are transported between locations.However, not all providers will agree, because should the provider have extensive routing and BGP in-house knowledge then the added complexity is certainly an issue but not a serious one.This is how high performance multi-layer switching came about.Layer 2 does not require additional special IP software for end users, corporation, and ISP.
It simply maps the incoming IP traffic onto a prebuilt and defined tunnel for transport across the MPLS network.
