As shown in Figure 8-8, when RouterA undergoes attacks, its CPU usage increases and network services are affected. To provide secure network services, the following attack defense functions are configured on RouterA:

  • Preventing malformed packet attacks

  • Limiting the rate of fragments to protect CPU and device resources

  • Preventing flood attacks:

    • Limiting the rate of TCP SYN packets to protect the CPU
    • Discarding UDP packets sent from specified ports
    • Limiting the rate of ICMP packets to protect the CPU
