The diagram of PPPoE process configuration for MikroTik or Cisco

In modern network architecture, providing reliable internet access to subscribers is essential. To grasp this setup fully, a diagram of PPPoE configuration can be invaluable. It is a fundamental requirement for Internet Service Providers (ISPs) and large enterprise networks. The Point-to-Point Protocol over Ethernet (PPPoE) has become the dominant standard. It accomplishes this by merging the widespread use of Ethernet networks with the robust features of the Point-to-Point Protocol (PPP). These features include authentication, access control, and billing.

1. PPPoE Process Diagram (Client to ISP)

This document provides a clear, visual diagram and a detailed explanation of the end-to-end PPPoE process configuration. It will outline the critical steps, starting from initial client-server discovery (PADI, PADO, PADR, PADS). Then, it will detail the final PPP negotiation and data session. The document also illustrates the parallel configuration commands and logic for both MikroTik and Cisco devices. The aim is to serve as a practical guide. It helps network engineers and administrators accurately deploy, troubleshoot, and manage scalable PPPoE access networks.

Below you’ll find both:

1. A diagram illustrating the PPPoE connection process, and
2. Example configurations for both MikroTik and Cisco routers to establish a PPPoE client connection.

+----------------+         +----------------+          +---------------------+
| Home Router    |         | ISP Access     |          | ISP Authentication  |
| (PPPoE Client) |  --->   | Concentrator   |  --->    | Server (Radius/AAA) |
+----------------+         +----------------+          +---------------------+
       |                          |                             |
       |--- PADI (Discovery) ---> |                             |
       |<-- PADO (Offer) --------|                             |
       |--- PADR (Request) ----->|                             |
       |<-- PADS (Session OK) ---|                             |
       |                          |--- Auth (CHAP/PAP) ------->|
       |                          |<-- Auth Success / Fail ----|
       |<----- IP Assigned -------|                             |
       |------ Internet Access -------------------------------->|

Key Phases:

• Discovery (PADI, PADO, PADR, PADS): Establishes communication.
• Authentication: Username/password verified by ISP.
• Session Established: IP is assigned; data flows.

2. PPPoE Configuration Examples

Configuring a PPPoE service requires a clear understanding of its logical process flow. This process includes distinct stages of discovery, session establishment, and data transfer. This process is universal in concept but varies in its command-line implementation between different network operating systems. MikroTik RouterOS is known for its cost-effectiveness and flexibility. Cisco IOS/IOS-XE is renowned for its enterprise-grade robustness and security. These are two of the most prevalent platforms for deploying PPPoE services.

A. MikroTik PPPoE Client Configuration

You can use Winbox, WebFig, or CLI. Here’s a CLI version:

# 1. Add a PPPoE client interface
/interface pppoe-client add \
    name=pppoe-out1 \
    interface=ether1 \
    user=your-username@isp \
    password=your-password \
    use-peer-dns=yes \
    add-default-route=yes \
    disabled=no

Explanation:

• interface=ether1: This is your WAN port connected to the ISP modem or line.
• user / password: Your ISP-provided PPPoE credentials.
• use-peer-dns=yes: Accept DNS from ISP.
• add-default-route=yes: Adds default internet route through PPPoE.

B. Cisco Router PPPoE Configuration

For Cisco IOS devices, PPPoE requires a Dialer interface:

! 1. Configure Ethernet interface connected to the modem
interface Ethernet0
 no ip address
 pppoe enable
 pppoe-client dial-pool-number 1

! 2. Create a dialer interface
interface Dialer1
 ip address negotiated
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp chap hostname your-username@isp
 ppp chap password your-password
 ppp pap sent-username your-username@isp password your-password
!
ip route 0.0.0.0 0.0.0.0 Dialer1

Explanation:

• pppoe enable: Enables PPPoE client mode on Ethernet.
• dialer pool: Logical link for managing the session.
• ppp chap/pap: Authentication methods.
• ip address negotiated: IP will be assigned by the ISP.
• The default route via Dialer1 enables internet access.

The PPPoE process is a crucial mechanism for authenticated Internet access used by ISPs around the world. It includes multiple handshake steps (PADI, PADO, PADR, PADS), authentication via PAP or CHAP, and IP address allocation. MikroTik and Cisco routers both support PPPoE with clear configuration paths. MikroTik uses a direct PPPoE client on an interface, while Cisco uses a dialer-based model for session management.
