ATM for Subscriber Access Encapsulation Types Overview
To enable subscriber access to an MX Series router over an ATM network, you can create any of the following configurations on Modular Port Concentrator/Modular Interface Card (MPC/MIC) interfaces that use the ATM MIC with SFP:
- PPP-over-Ethernet-over-ATM (PPPoE-over ATM) with a dynamic or 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 (IPoE-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
As part of the configuration procedure, you must specify the appropriate encapsulation type for your configuration on the ATM logical interface.
Table 1 lists and describes the encapsulation type you must specify as part of the encapsulation statement when you configure the ATM logical interface for each supported configuration.
Table 1: Encapsulation Types for Supported ATM Subscriber Access Configurations
ATM Subscriber Access Configuration | Encapsulation Type | Description |
|---|---|---|
PPPoE-over-ATM with dynamic pp0 subscriber interface | ppp-over-ether-over-atm-llc | PPPoE-over-ATM encapsulation with logical link control (LLC) |
PPPoE-over-ATM with static pp0 subscriber interface | ppp-over-ether-over-atm-llc | PPPoE-over-ATM encapsulation with LLC |
IP-over-ATM (IPoA) | atm-snap | ATM subnetwork attachment point (SNAP) encapsulation for IPoA with LLC |
atm-vc-mux | ATM VC multiplex encapsulation for IPoA with virtual circuit (VC) multiplexing | |
IP-over-Ethernet-over-ATM (IPoE-over-ATM) | ether-over-atm-llc | Ethernet-over-ATM encapsulation with LLC |
PPP-over-ATM (PPPoA) | atm-ppp-llc (for PPPoA with logical link control) | PPP-over-AAL5 encapsulation with LLC |
atm-ppp-vc-mux (for PPPoA with virtual circuit multiplexing) | PPP-over-AAL5 encapsulation with VC multiplexing |
