In which stage of PPPoE the MAC addresses of the endpoints are exchanged?

The Point-to-Point Protocol over Ethernet ( PPPoE ) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999 in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP’s IP network and from there to the rest of the Internet.A 2005 networking book noted that “Most DSL providers use …

PPP can assign IP addresses to these virtual interfaces and these IP addresses can be used for example to route between the networks on both sides of the tunnel.

Sun Oct 26 2003 13:30:00 GMT-0500 (Eastern Standard Time) · In computer networking Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It uses encryption (‘hiding’) only for its own control messages (using an optional pre-shared secret) and does not provide any encryption or confidentiality of content by itself.

Ethernet (/ ˈ iː θ ər n ɛ t /) is a family of wired computer networking technologies commonly used in local area networks (LAN) metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.Ethernet has since been refined to support higher bit rates a greater number of nodes and longer link distances …
