Configuring a Pseudowire Subscriber Logical Interface
A pseudowire subscriber logical interface terminates an MPLS pseudowire tunnel from an access node to the MX Series router that hosts subscriber management, and enables you to perform subscriber management services at the interface.
To create a pseudowire subscriber logical interface, you configure the following characteristics:
- Specify the number of pseudowire logical interfaces that
the router can support.
See Configuring the Maximum Number of Pseudowire Logical Interface Devices Supported on the Router.
- Configure the pseudowire subscriber logical interface
device.
See Configuring a Pseudowire Subscriber Logical Interface Device.
- Configure the transport logical interface.
See Configuring the Transport Logical Interface for a Pseudowire Subscriber Logical Interface.
- Configure the signaling for the pseudowire subscriber
interface. You can use either Layer 2 circuit signaling or Layer 2
VPN signaling. The two signaling types are mutually exclusive for
a given pseudowire.
- To configure Layer 2 circuit signaling, see Configuring Layer 2 Circuit Signaling for Pseudowire Subscriber Logical Interfaces.
- To configure Layer 2 VPN signaling, see Configuring Layer 2 VPN Signaling for Pseudowire Subscriber Logical Interfaces.
- Configure the service logical interface.
See Configuring the Service Logical Interface for a Pseudowire Subscriber Logical Interface.
- Configure the underlying interface device.
See Configuring an Underlying Interface for Dynamic PPPoE Subscriber Interfaces.
- Configure CoS parameters and BA classification.
See CoS Configuration Overview for MPLS Pseudowire Subscriber Interfaces .
- (Optional) Associate a dynamic profile with the pseudowire
subscriber logical interface.
You can associate DHCP, PPPoE, and IP demux dynamic profiles with pseudowire subscriber logical interfaces. The support is similar to the typical Ethernet interface support.
Note: When using a PPPoE dynamic profile to create a pseudowire subscriber logical interface over a demux interface device, the dynamic profile must explicitly specify the correct pseudowire interface device over which the interface is created. The dynamic profile does not automatically create the interface over the demux0 interface device, as is the case with a VLAN demux interface.
For additional information about associating dynamic profiles to interfaces, see Dynamic Profile Attachment to DHCP Subscriber Interfaces Overview and Configuring VLAN Interfaces to Use Dynamic Profiles.
- (Optional) Configure interface set support for pseudowire subscriber logical interfaces.
- (Optional) Stack PPPoE logical interfaces over a pseudowire logical device.
