also acts as the DF.
Configuration restrictions and guidelines
When you enable IPv6 PIM passive mode, follow these restrictions and guidelines:
•
This feature takes effect only when IPv6 PIM-DM or IPv6 PIM-SM is enabled on the interface.
•
To avoid duplicate multicast data transmission and flow loop, do not enable this feature on a
shared-media LAN with multiple IPv6 PIM routers.

Enabling IPv6 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.

Enabling SNMP notifications for IPv6 PIM
To report critical IPv6 PIM events to an NMS, enable SNMP notifications for IPv6 PIM. For PIM event
notifications to be sent correctly, you must also configure SNMP as described in
Network
Management and Monitoring Configuration Guide
