The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP in RouterOS is based on RFC 1661 standard.


The basic purpose of PPP at this point is to transport Layer-3 packets across a Data Link layer point-to-point link.  Packets between both peers are assumed to deliver in order. 

PPP is comprised of three main components:

  1.  A method for encapsulating multi-protocol datagrams.
  2.  A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection. 
  3. A family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.

Detailed PPP packet processing in RouterOS you can see in the Packet Flow Diagram.
