When it completes, both peers know the PPPoE SESSION_ID and the peer's Ethernet address, which together define the PPPoE session uniquely: There are four steps to the Discovery stage.

MikroTik RouterOS server (access concentrator) to multiple PPPoE clients (clients are available for almost all operating systems and most routers).MikroTik RouterOS PPPoE client to any PPPoE server (access concentrator).PPPoE provides the ability to connect a network of hosts over a simple bridging access device to a remote Access Concentrator. It is advised not to use static IP addresses or DHCP on the same interfaces as PPPoE for obvious security reasons. PPPoE standard is defined in RFC 2516. The PPPoE client and server work over any Layer2 Ethernet level interface on the router, for example, Wireless, Ethernet, EoIP, etc. Generally speaking, PPPoE is used to hand out IP addresses to clients based on authentication by username (and also if required, by workstation) as opposed to workstation only authentication where static IP addresses or DHCP are used. Point to Point over Ethernet (PPPoE) is simply a method of encapsulating PPP packets into Ethernet frames. PPPoE is an extension of the standard Point to Point Protocol (PPP) and it the successor of PPPoA.
