The present disclosure relates to a method to propagate Pseudowire (PWE) administrative state and gracefully handle PWE blocking. New STATUS codes are described for representing the administrative state in a PWE group. The approach described herein provides a method via which the Provider Edge (PE) router can propagate the PWE Blocking status due to a fault or an administrative action. The receiving PE router can consult the local policy on how to process the fault or administration action on the PWE at the remote end, e.g., this approach facilitates the special processing of administrative actions. The proposed solution works with already supported STATUS signaling, works independent of PWEs being Static PWE or Dynamic PWEs, and the proposed new Status code/value allows old PEs to also work with the new status code.
