Techniques are described herein for resolving conflicts in role statuses assigned to a customer edge device by multiple provider edge devices in communication with that customer edge device. In embodiments, such techniques may involve receiving information about a customer edge device in communication with the first provider edge device and storing, based on the information about the customer edge device, an indication of a first role status of the customer edge device. The techniques may further involve receiving, from at least one second provider edge device in communication with the customer edge device, an advertisement message that includes a second role status of the customer edge device, comparing the first role status to the second role status, and upon determining that the first role status does not match the second role status, updating the first role status of the customer edge device.
