Chapter 9 The VPN Transport Screens
It is necessary to encapsulate the Ethernet pseudowire since the WiMAX
connection is IP-only. MPLS information is carried in a packet's Ethernet header
and, without encapsulation, would be stripped from the packet prior to the
packet's transmission over the WiMAX link.
The following figure shows the VPLS connection between your WiMAX Device (A)
and your service provider's router (B), consisting of GRE-encapsulated Ethernet
pseudowire traffic.
