Configuring ATM for Subscriber Access

On MX Series routers with MPC/MIC interfaces that use the ATM MIC with SFP, you can create the following configurations to enable subscribers to access the router over an ATM network using ATM Adaptation Layer 5 (AAL5) permanent virtual connections (PVCs):

  • PPP-over-Ethernet-over-ATM (PPPoE-over ATM) with a dynamic PPPoE (pp0) subscriber interface over a static ATM underlying interface

  • PPP-over-Ethernet-over-ATM (PPPoE-over ATM) with a static PPPoE (pp0) subscriber interface over a static ATM underlying interface

  • Routed IP-over-ATM (IPoA) with a static IPv4 or IPv6 subscriber interface over a static ATM underlying interface

  • Bridged IP-over-Ethernet-over-ATM with a static IPv4 or IPv6 subscriber interface over a static ATM underlying interface

  • PPP-over-ATM (PPPoA) with a static PPP subscriber interface over a static ATM underlying interface

  • Concurrent PPP-over-Ethernet-over-ATM interfaces and IP-over-Ethernet-over-ATM interfaces on a single ATM PVC

Before you begin:

  1. Make sure the MX Series router you are using has Modular Port Concentrator/Modular Interface Card (MPC/MIC) interfaces and an ATM MIC with SFP (Model Number MIC-3D-8OC3-2OC12-ATM) installed and operational.

    • For information about compatible MPCs for the ATM MIC with SFP, see the MX Series Interface Module Reference.

    • For information about installing MPCs and MICs in an MX Series router, see the Hardware Guide for your MX Series router model.

  2. Make sure you understand how to configure and use static ATM interfaces.

    See ATM Interfaces Overview.

  3. If your configuration includes dynamic profiles for PPPoE, class of service (CoS) attributes, or standard firewall filters, make sure you understand how to configure these attributes and apply them to the subscriber interface.

To configure ATM for subscriber access on an MX Series router:

  1. For a PPPoE-over-ATM configuration with a dynamic PPPoE (pp0) subscriber interface, create a dynamic profile that defines the pp0 subscriber interface.

    See Example: Configuring a Dynamic PPPoE Subscriber Interface over ATM.

  2. Configure one or more virtual path identifiers (VPIs) on the ATM physical interface.
  3. Configure the ATM logical subscriber interface.
    1. Configure the appropriate encapsulation type for your configuration.

      See ATM for Subscriber Access Encapsulation Types Overview.

    2. Configure a virtual circuit identifier (VCI) for each VPI configured on the ATM logical interface.
    3. Configure other interface-specific properties as needed for your configuration.

      See Guidelines for Configuring ATM for Subscriber Access.

  4. For static PPPoE-over-ATM configurations, define the static PPPoE (pp0) subscriber interface at the [edit interfaces pp0 unit logical-unit-number] hierarchy level.

    See Example: Configuring a Static PPPoE Subscriber Interface over ATM.

  5. (Optional) Configure RADIUS server options for ATM.

    See RADIUS Servers and Parameters for Subscriber Access and Configuring the RADIUS NAS-Port Extended Format for ATM Interfaces.

  6. (Optional) Verify the configuration for ATM subscriber access.

    See Verifying and Managing ATM Configurations for Subscriber Access.
