What is L2VPNs?

Layer 2 VPNs (L2VPNs) are used to establish a virtual private network at the data link layer (Layer 2) of the OSI model. They allow Ethernet frames or other Layer 2 protocols to be transported across a network, typically an IP network, as if they were on the same physical network. This is commonly used to connect geographically separated sites within the same organization, enabling them to function as a single bridged network.
