Usage Guidelines

Usage Scenario

A switch can receive multiple PIM State-Refresh messages in a short period. Some of the messages are the same. To avoid duplicate messages, you can run the state-refresh-rate-limit command to set the period to wait to receive the next State-Refresh message.

Before the State-Refresh timer times out, the switch discards the received duplicate State-Refresh messages.
After the State-Refresh timer times out, the switch can receive the next State-Refresh message.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command in the public network instance or VPN instance.

Precautions

This command is valid for only PIM-DM.

Example

# Set the minimum period to wait to receive the next PIM State-Refresh message to 45s in the PIM view of public network instance.
