Enabling PIM NSR
About PIM NSR
This feature enables PIM to back up protocol state information and data, including PIM neighbor information and routes, from the active process to the standby process. The standby process immediately takes over when the active process fails. Use this feature to avoid route flapping and forwarding interruption for PIM when an active/standby switchover occurs.
