Methods, systems, and computer program products for individually identifying and disabling circular routes from active routes to a common destination are disclosed. According to one method, multiple active routes are maintained to a common destination. Congestion is detected on a signaling link associated with at least one of the routes. In response to detecting the congestion, at least one of the routes is tested for circularity. One of the routes is identified as circular based on the testing. In response to identifying the route as circular, the route is disabled and use of the remaining active routes to the destination is continued.
