This chapter describes the IP Event Dampening feature, interface state change events and thresholds, affected components and supported protocols, guidelines and limitations, and how to enable and verify IP event dampening on the Cisco 8000 Series Router.
IP event dampening
This topic describes how the IP Event Dampening feature uses a configurable exponential decay mechanism to suppress the effects of excessive interface flapping on routing protocols and routing tables, so that the network stays stable and converges faster.
Guidelines and limitations for IP event dampening
This topic describes the guidelines and limitations to configure IP event dampening, including how penalties accumulate and decay, how the interface transitions between the dampened and unsuppressed states, and the supported interfaces and IP client behavior.
Enable IP event dampening
This topic describes how to enable the IP Event Dampening feature on an interface by using the dampening command in interface configuration mode, and how to verify the configuration by using the show commands.
