Traffic Processing Method, Apparatus, and Network Device

A network device obtains Border Gateway Protocol (BGP) flow specification (FlowSpec) information, and generates, based on the BGP FlowSpec information, a first forwarding information base (FIB) table entry including a first prefix and an action, where the BGP FlowSpec information indicates to perform an action on traffic matching a filter condition, where the filter condition includes an attribute of a destination address, where the first FIB table entry indicates the network device to perform the action on the traffic matching the first prefix, and where an attribute of the first prefix is the same as the attribute of the destination address in the filter condition.
