Abstract
In one embodiment, a method includes receiving, by a provider edge (PE) device, a transport layer status message indicative of a defect on a pseudowire (PW) running across a core of a service provider (SP) network. The status message is translated to a service layer message indicative of the defect. The service layer message is then transmitted across an access domain of the SP network.
