hardware-drop-disable
Disables passive multicast route insertion (PMRI).
Command Default
PMRI is enabled.
Modes
PIM router configuration mode
Usage Guidelines
The
no form of this command restores the default and enables PMRI.
To prevent unwanted multicast traffic from being sent to the CPU, PIM routing and
PMRI can be used together to ensure that multicast streams are forwarded out only
on ports with interested receivers and unwanted traffic is dropped in hardware on
Layer 3 switches. To disable this process, use the
hardware-drop-disable command.
Note: Disabling hardware-drop does not immediately take away existing hardware-drop entries,
they will go through the normal route aging processing when the traffic stops.
