Abstract
Scalable data forwarding techniques in a switched network are described herein. In one embodiment, an example of a process for forwarding data includes, in response to a first packet received from a first local node over a local area network (LAN) and destined to a first remote node over a provider network, a provider edge (PE) device of the provider network substituting a source MAC (media access control) address of the first packet with a virtual MAC address associated with the PE device, and the PE device transmitting the first packet having the virtual MAC address as the source MAC address to the first remote node over the provider network. Other methods and apparatuses are also described.
