Which four types of PPPoE packets are exchanged during the PPPoE discovery phase?

PPPoE stages

PPPoE discovery.
PPP session.
Client to server: Initiation (PADI)
Server to client: Offer (PADO)
Client to server: request (PADR)
Server to client: session-confirmation (PADS)
Either end to other end: termination (PADT)

Should I enable PPPoE?

PPPoE needs to be configured correctly before a user can actually connect to the Internet, however, DHCP doesn’t need to be configured and is basically plug and play. So using DHCP to connect to an ISP eliminates the problems that are associated with PPPoE.

What PPPoE means?

Point-to-Point Protocol over Ethernet
Point-to-Point Protocol over Ethernet (PPPoE) combines PPP, which typically runs over broadband connections, with the Ethernet link-layer protocol that allows users to connect to a network of hosts over a bridge or access concentrator.

What PPPoE is and what it allows to do?

PPPoE is an acronym that stands for Point-to-Point Protocol over Ethernet. PPPoE was designed for managing how data is transmitted over Ethernet networks (cable networks), and it allows a single server connection to be divided between multiple clients, using Ethernet.

What does the discovery stage of PPPoE do?

The PPPoE Discovery stage does exactly this. In addition it also helps establish a Session ID that can be used for further exchange of packets. Once the MAC address of the peer is known and a session has been established, the Session stage will start.

What are the stages of PPPoE over Ethernet?

There are two stages in PPPoE connectivity, discovery and session. While initializing a Point to Point Protocol over Ethernet session, A host must identify the MAC address of the peer device. While connecting to a server, there are multiple sessions, PADI, PADO, PADR, and PADS

What is the destination address of PPPoE active discovery?

In response to the PADI packet, one or more routers or access concentrators sends an Offer message PPPoE Active Discovery Offer to the respective device on the LAN. Here the destination address is the unicast address of the host, who requested PADI.

When to send Padt, PPPoE active discovery termination?

At the PADS step PPPoE connectivity gots completed. If it is desired to break this session at any stage after the connection establishment, then a termination message is sent either by the router or the host. This message is called PADT, PPPoE Active Discovery Termination.
