A Metro Ethernet Network with MX Series Routers
What would a Metro Ethernet network with Juniper Networks MX Series 3D Universal
Edge Router look like? It is very likely that the Metro Ethernet network will place MX Series
routers at the edge of a VPLS and MPLS core network.
The VLAN labels in the packet are stacked with MPLS labels, as shown in Figure 2 on
page 15. For a more detailed examination of this type of Metro Ethernet network, see
“Example: Configuring a Provider VPLS Network with Normalized VLAN Tags” on page 51.

Another possible configuration, this one without the VPLS and MPLS core, is shown in
Figure 3 on page 16.
