Question

What should I be aware of when using subscriber management to create subscriber interfaces over point-to-point MPLS pseudowires?

Answer

For Pseudowire Logical Interfaces:

  • When using a PPPoE dynamic profile to create a pseudowire subscriber logical interface over a demultiplexing (demux) interface device, the dynamic profile must explicitly specify the correct pseudowire interface device over which the interface is created. For more information, click Configuring a Pseudowire Subscriber Logical Interface.

For Pseudowire Logical Interface Devices:

  • You should ensure that you change the MAC address prior to passing traffic or binding subscribers on the pseudowire port. Changing the MAC address when the pseudowire port is active can negatively impact network performance until adjacencies learn of the new MAC address.
