pim timer dr-switch-delay
Function
The pim timer dr-switch-delay command enables PIM DR switching delay and configures the delay on an interface. When the interface changed from a DR to a non-DR, the interface continues to forward data before the delay expires.
The undo pim timer dr-switch-delay command disables PIM DR switching delay on the interface.
By default, when the interface changes from a DR to a non-DR, the interface stops forwarding data immediately.
Parameters
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the delay. | The value is an integer that ranges from 10 to 3600, in seconds. |
Usage Guidelines
Usage Scenario
If the DR on a shared network segment becomes the non-DR, original multicast forwarding entries will be deleted immediately, causing multicast data interruption in a short time. To solve the problem, set the DR switching delay. Original multicast forwarding entries still take effect until the delay is reached.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Precautions
This command is valid for only PIM-SM.
