PPP
Overview
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.
Introduction
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 be delivered in order.
PPP is comprised of three main components:
- A method for encapsulating multi-protocol datagrams.
- A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection.
- A family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.
For detailed PPP packet processing in RouterOS, you can see in the Packet Flow Diagram.

PPP Client example
This is an example of how to add a client using an exposed serial port from an LTE modem.
/interface/ppp-client/add apn=yourapn dial-on-demand=no disabled=no port=usb2
The dial-on-demand should be set to 'no' for a continuous connection.
PPP Server

If you see the message “A newer version of modem firmware is available!” and you want to upgrade the firmware of your BG77 modem, use this command:
/interface/ppp-client/firmware-upgrade [find] upgrade=yes
