Enabling IPv6 PIM NSR
About PIM NSR
This feature enables IPv6 PIM to back up protocol state information, including IPv6 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 IPv6 PIM when an active/standby switchover occurs.
