What is PPPoE and what does it mean?

What is PPPoE and what does it mean?

What is PPPoE and what does it mean? PPPoE is an acronym that stands for Point-to-Point Protocol over Ethernet. PPPoE is a networking protocol that derived from another, older protocol, called PPP, which you guessed, stands for Point-to-Point Protocol.

What is PPPoE (point to Point Protocol over Ethernet)?

Point-to-Point Protocol over Ethernet (PPPoE) refers to the system used in connecting multiple devices, such as computers, laptops, smartphones, etc., on an Ethernet LAN (local area network).

Why is dialing into the PPPoE server maintained constantly?

On Cisco devices the dialing into the PPPoE server is maintained constantly due to CDP (Cisco Discovery Protocol) being the interesting traffic in addition to PPP keepalive messages being transmitted for failure detection.

What is PPPoE dial-pool 1?

Instead, we are telling to use PPPoE, and that the PPPoE configuration is in the dial-pool number 1. The Dialer is a logical interface that represents the termination of the PPPoE connection. The Ethernet interface just connects the underlying Ethernet link that encapsulates PPP frames.

Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol that facilitates communication between network endpoints. PPPoE encapsulates Point-to-Point Protocol (PPP) frames inside Ethernet frames, offering the same benefits as PPP, while providing connectivity across Ethernet networks.

Should we use DHCP over PPPoE or vice versa?

PPPoE vs DHCP are not relevant items and the debate between them lasts for a long time: PPPoE or Point-to-Point Protocol over Ethernet is commonly used to connect to an ISP while DHCP or Dynamic Host Configuration Protocol is a protocol for obtaining IP addresses to clients computer. So which is better? Should we use DHCP over PPPoE or vice versa.

What do I need from my ISP to set up PPPoE?

If your Internet Service Provider uses PPPoE, then you need at least two things, from the ISP: If your ISP did not provide you with a router (nor did you buy yourself one), then you have to configure the PPPoE connection manually, on your computer.
