摘要： A method of operating a network device is provided. The method may include updating a software forwarding table in response to a link between the network device and one or more next hops device being disconnected or connected. The software forwarding table may list next hop devices currently available or connected to the network device for a given destination prefix. The method may include determining whether to update a hardware forwarding table also associated with the given destination prefix depending on whether one or more criteria have been satisfied. The hardware forwarding table may be updated in accordance with a resilient mode or an ordered mode. The resilient mode takes into account history information associated with the hardware forwarding table, whereas the ordered mode does not take into account the history information associated with the hardware forwarding table.
