Abstract
Methods and apparatuses for rapid TRILL convergence are disclosed herein. The methods can be implemented in a network including a plurality of RBridges or in a cloud network environment including a plurality of cloud switch domains. An example method for rapid TRILL convergence can include: Executing a spanning tree protocol (STP) for network topology in a network; and executing a Hello protocol for control and forwarding at the RBridge. The Hello protocol can be configured to elect a designated RBridge and assign an appointed forwarder. The method can also include assigning a transient appointed forwarder during a period of time between convergence of the STP and convergence of the Hello protocol. The transient appointed forwarder can be configured to forward frames in the network during the period of time between convergence of the STP and convergence of the Hello protocol.
