Usage Guidelines

When a device receives a huge number of packets with route-alert options that increase the traffic loads, performance of the device is affected. The discard ra command is used to discard IP packets with route-alert options, which reduces pressure on CPU and improves network performance and security.

The discard ra command applies to only incoming packets.
