PPPoE Client Overview
The Point-to-Point over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside Ethernet frame. PPPoE combines Ethernet and PPP, to provide an authenticated method of assigning IP addresses to client systems.
The Cisco Wireless Gateway for LoRaWAN can be configured as a PPPoE client, so that a tunnel can be established for the router to access the WAN.
At system initialization, the PPPoE client establishes a session with the access concentrator by exchanging a series of packets. Once the session is established, a PPP link is set up, which includes authentication using Password Authentication protocol (PAP). Once the PPP session is established, each packet is encapsulated in the PPPoE and PPP headers.
