Systems and methods for deadlock avoidance within MPLS networks

Abstract:

The disclosed method may include (1) detecting, within at least one interface of a first endpoint device, a connectivity failure that disrupts a Layer 2 service based on an MPLS connection between the interface of the first endpoint device and at least one interface of a second endpoint device, (2) in response to detecting the connectivity failure, sending, to the second endpoint device, a first bidirectional BFD packet that prompts the second endpoint device to at least partially disable the interface of the second endpoint device, (3) determining that the connectivity failure has been corrected, and then (4) re-establishing the Layer 2 service based on the MPLS connection by sending, to the second endpoint device, a second BFD packet that prompts the second endpoint device to re-enable the interface of the second endpoint device. Various other apparatuses, systems, and methods are also disclosed.
