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.

First claim

What is claimed:

1. A method for rapid Transparent Interconnect of Lots of Links (TRILL) convergence in a network having a plurality of RBridges, comprising:
executing a spanning tree protocol (STP) for network topology in the network;
executing a Hello protocol for control and forwarding at an RBridge, the Hello protocol being configured to elect a designated RBridge and assign an appointed forwarder; and
during a period of time between convergence of the STP and convergence…
