Overview
There are a great variety of network protocols, including such routing protocols as OSPF, BGP,
RIP and etc. Protocol communication is realized by exchanging packets between different
devices, and the exchange packets must be delivered to the CPU in order to be processed by
respective protocols. Once a protocol is running on the network device, a "window" is opened
to potential attackers. If the attacker sends excessive protocol packets to the network device,
the CPU resource of the device will be heavily consumed, and the device may not work
properly.
