PPPoE stands for Point-to-Point Protocol over Ethernet. It is a networking protocol used to establish and maintain a connection between a client device and an internet service provider (ISP) using Ethernet technology.
PPPoE is commonly used in DSL internet connections, where the client device, typically a computer or router, connects to the ISP through a DSL modem. The PPPoE protocol is used to encapsulate PPP frames within Ethernet frames, allowing the client device to communicate with the ISP over an Ethernet connection.
To establish a PPPoE connection, the client device must first authenticate with the ISP using a username and password. Once authenticated, the client device can use PPP to negotiate network settings such as IP address and DNS server information.
Overall, PPPoE provides a secure and reliable way for client devices to connect to the internet through an ISP that uses Ethernet technology.
