Enabling PIM passive mode
To guard against PIM hello spoofing, you can enable PIM passive mode on a receiver-side interface.
The PIM passive interface cannot receive or forward PIM protocol messages (excluding register,
register-stop and C-RP-Adv messages), and it acts as the DR on the subnet. In BIDIR-PIM, it also
acts as the DF.
Configuration restrictions and guidelines
When you enable PIM passive mode, follow these restrictions and guidelines:
This feature takes effect only when PIM-DM or 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 PIM routers.
