IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered
across an Ethernet network, without using PPP encapsulation. They are routed
between the Ethernet interface and the WAN interface and then formatted so that
they can be understood in a bridged environment. For instance, it encapsulates
routed Ethernet frames into bridged Ethernet cells.
