Abstract
The reliability of the connection of a client edge (CE) device to a core network may be improved using redundant provider edge (PE) devices. A first of the PE devices may monitor a connection to the core network, where the PE device acts as a root device in a set of devices that implement a spanning tree using a spanning tree protocol and where a second PE device in the set of devices additionally connects to the core network. The PE device may additionally detect failure of the connection of the PE device to the core network; and change, in response to the detected failure of the connection, a spanning tree protocol priority value of the device to a value having a lower priority than that of the second PE device.
