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

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.
  2. Configure one or more VPIs on the ATM physical interface.
  3. Configure IPoE-over-ATM encapsulation on the ATM logical interface.
  4. Configure the VCI for the ATM logical interface.
  5. Configure one or both of the following IP protocol families and addresses as appropriate for your network configuration.

    • For IPv4 (inet):

    • For IPv6 (inet6):

  6. Configure PPPoE-over-ATM as a supported family by associating a PPPoE dynamic profile with the ATM logical interface.

    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.

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.
