Configuring Concurrent PPPoE-over-ATM and IPoE-over-ATM Subscriber Interfaces on an ATM PVC

date_range 06-Dec-23

To configure concurrent PPPoE-over-ATM and IPoE-over-ATM subscriber interfaces on a single ATM PVC, you configure the ATM logical interface as an IPoE-over-ATM interface by specifying the ether-over-atm-llc encapsulation type. You then use the family pppoe stanza at the [edit interfaces at-fpc/pic/port unit logical-unit-number] hierarchy level to configure PPPoE-over-ATM as a supported family.

When the router detects the family pppoe stanza and the IPoE-over-ATM encapsulation, it identifies the configuration as concurrently supporting both PPPoE-over-ATM and IPoE-over-ATM on the same ATM PVC.

Before you begin:

Configure a PPPoE dynamic profile.

See Configuring a PPPoE Dynamic Profile.

To configure concurrent PPPoE-over-ATM and IPoE-over-ATM subscriber interfaces on an ATM PVC:

  1. Specify that you want to configure ATM-specific options on the physical interface.
    content_copy zoom_out_map
    [edit interfaces at-fpc/pic/port]
    user@host# edit atm-options
    
  2. Configure one or more VPIs on the ATM physical interface.
    content_copy zoom_out_map
    [edit interfaces at-fpc/pic/port atm-options]
    user@host# set vpi vpi-identifier
    
  3. Configure IPoE-over-ATM encapsulation on the ATM logical interface.
    content_copy zoom_out_map
    [edit interfaces at-fpc/pic/port unit logical-unit-number]
    user@host# set encapsulation ether-over-atm-llc
    
  4. Configure the VCI for the ATM logical interface.
    content_copy zoom_out_map
    [edit interfaces at-fpc/pic/port unit logical-unit-number]
    user@host# set vci vpi-identifier.vci-identifier
    
  5. Configure one or both of the following IP protocol families and addresses as appropriate for your network configuration.
    • For IPv4 (inet):

      content_copy zoom_out_map
      [edit interfaces at-fpc/pic/port unit logical-unit-number]
      user@host# set family inet address address
      
    • For IPv6 (inet6):

      content_copy zoom_out_map
      [edit interfaces at-fpc/pic/port unit logical-unit-number]
      user@host# set family inet6 address address
      
  6. Configure PPPoE-over-ATM as a supported family by associating a PPPoE dynamic profile with the ATM logical interface.
    content_copy zoom_out_map
    [edit interfaces at-fpc/pic/port unit logical-unit-number]
    user@host# set family pppoe dynamic-profile profile-name
    

    The dynamic profile defines PPPoE-specific options for the pp0 logical interface, and establishes the PPPoE session. When the PPPoE-over-ATM session is established, PPPoE-over-ATM features operate on the PPPoE-over-ATM session interface.

  7. Enable the IPv6 neighbor discovery protocol for the ATM logical interface.
    content_copy zoom_out_map
    [edit protocols router-advertisement interface at-fpc/pic/port.logical-unit-number]
    user@host# set prefix prefix
    

The following example configures concurrent support for IPv4-over-Ethernet-over-ATM, IPv6-over-Ethernet-over-ATM, and PPPoE-over-ATM subscriber interfaces on an ATM PVC with VPI 10 and VCI 200. ATM logical interface at-1/2/0.200 is configured with IPoE-over-ATM encapsulation (ether-over-atm-llc). The family pppoe statement configures PPPoE-over-ATM as a supported family by associating a PPPoE dynamic profile named pppoeoa-profile with interface at-1/2/0.200.
