<p>Embodiments of the present invention provide a method and a service provider-end provider edge device for triggering a route failover. The method includes: establishing a binding relationship between a first neighbor relationship and a second neighbor relationship, where the first neighbor relationship is between a service provider-end provider edge device and a routing device of a backbone network and the second neighbor relationship is between the service provider-end provider edge device and a user-end provider edge device; detecting whether the first neighbor relationship is broken; and if so, triggering the user-end provider edge device corresponding to the second neighbor relationship to perform a route failover. The service provider-end provider edge device in the present invention includes: a binding module, a detection module, and a trigger module. With the present invention, the service provider-end provider edge device can be triggered to perform a route failover when a link fails.</p> |
