Abstract
A method and apparatus in provided which enables fast layer 2 reconfiguration in a network that includes Routing Bridges. Each Routing Bridge stores, for each forwarding target, identifiers of a primary next Rbridge and an alternate next Rbridge. The forwarding target may be a network end node, or an Egress Rbridge associated with the network end node. In response to a trigger condition, layer 2 communications are selectively switched from a path that includes the primary next Rbridge device to a path that includes the alternate next Rbridge device.
