Embodiments of the invention relate to Layer 2 network extensions over Layer 3 networks using packages. Techniques are disclosed for session-based routing within a Layer 2 (L2) network of an Open System Interconnect (OSI) model extended over a Layer 3 (L3) network. In one example, an L2 network connects a first client device to a first router and a second client device to a second router. And the L3 network is connected with the first router and the second router. A first router receives, from a first client device, a non-session-based L2 frame destined for a second client device. The first router forms an L3 packet including an L3 header specifying L3 addresses of the first router and the second router and a protocol of L3 service selection based on the L2 frame, a payload including the L2 frame, and metadata including a session identifier clearly identifying the L2 frame, and forwards the L3 packet to the second router. The second router restores the L2 frame from the payload and forwards the L2 frame to the second client device.
