I can have one site as a hub and others as spokes and speak via the hub? Using traditional L2TPV3 config, how can I use multiple Xconnects for the same VLAN on the same interface? Worst case scenario, I can run VPLS over MPLS (Have our new routers as VPLS PEs), but seems overkill. The two endpoints of an L2TP tunnel are called the LAC (L2TP Access Concentrator) and the LNS (L2TP Network Server). One of the key difference between automatic 6to4 tunnels vs manually configured tunnels is that the tunnel itself is not a Point-to-Point, but rather a Point-to-Multipoint tunnel. The client machine at the end of a VPN could be a threat and a source of attack; this has no connection with VPN design and most VPN providers leave it to system administration to secure. The tunnel mode generates an additional IP header, occupying more bandwidth than the transport mode. EPL Point to Point EVP-LAN Multipoint-to-Multipoint.
