Configuring EtoPPP and EtoFR

Ethernet to PPP (EtoPPP) converts on the data link layer between Ethernet and PPP for IP packets. Similarly, Ethernet to Frame Relay (EtoFR) converts on the link layer between Ethernet and Frame Relay for IP packets. With EtoPPP or EtoFR, a device encapsulates an Ethernet-encapsulated IP packet with PPP or FR encapsulation, and then forwards the packet rather than routes the packet. EtoPPP and EtoFR achieves high-performance Layer 2 switching between different types of links.
