They claim they need layer-2 virtual networks to support existing applications (like Microsoft's load balancing marvels) and rely on flooding (emulated with IP multicast) to build the remote-MAC-to-remote-IP mappings in hypervisor virtual switches. Cisco.Press.Metro.Ethernet.eBook-KB Cisco.Press.Mobile.IP.Technology.and.Applications.May.2005. Operation of FRoMPLS is a bit different in l2ptv3. With 802.1Q tunneling, company The Cisco Catalyst 3750 Metro Series supports equally architecture choices since the PE-CLE swap inside the H-VPLS accessibility network. Enterprisees who wish to appear connected on the same LAN segment can use this service. Open VPN - building and integrating virtual private networks 6.

I wouldn't recommend the above one and would rather go with MPLS Fundamentals (by far the best MPLS book around) and Layer 2 VPNs. VPLS is a layer 2 VPN architecture which was designed for multipoint connectivity and broadcast capability. Nicira's Network Virtualization Platform is way better – it has a central control plane that uses OpenFlow to distribute MAC-to-IP mapping information to individual hypervisors. The Q.922 header isn't stripped in that l2vpn mode and the dlci will be rewritten in the other endpoint while other link-layer operation is the same. 802.1Q tunneling allows support organizations to supply a Layer two VPN service, often referred to as Layer 2 transparent LAN products and services (TLS) or Ethernet LAN products and services, using a VLAN-in-VLAN hierarchy and marking the labeled packets.

It uses Layer 2 architecture to offer multipoint Ethernet VPNs that connect several sites over a metropolitan-area network (MAN) or wide-area network (WAN).
