摘要:
A multi-chassis network device sends state information to internal consumers within the multi-chassis device via a hierarchical distribution. As one example, a primary master routing engine within a control node of a multi-chassis router forwards state information to local routing engines within other chassis, which in turn distribute the state information to consumers on each chassis. Each local routing engine defers sending acknowledgement to the master routing engine until acknowledgements have been received from all consumers serviced by the local routing engine. Embodiments of the invention may reduce control plane data traffic and convergence times associated with distribution of state updates in the multi-chassis network device.
