The register-suppression-timeout command sets the timeout period during which a switch keeps the register suppression state.
The undo register-suppression-timeout command restores the default timeout period.
By default, a switch keeps the register suppression state for 60 seconds.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the timeout period during which the switch keeps the register suppression state. | The value is an integer that ranges from 11 to 3600, in seconds. |
Usage Scenario
After receiving a Register-Stop message from the RP, the switch immediately stops sending Register messages and enters the register suppression state.
The register-suppression-timeout command determines how long the switch keeps the register suppression state. When the timeout period expires, the switch (source DR) starts to send Register messages to the RP.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Configuration Impact
If the timeout period is too short, the RP receives burst multicast data more frequently. If the timeout period is too long, there will be a long delay for new receivers to join a group after an (S, G) entry on the RP times out.
You can use the probe-interval (IPv4) command to configure the switch to send null Register messages before the suppression timer times out. This configuration reduces burst Register messages and shortens the timeout period to reduce the delay for a new receiver to join a group.
Precautions
This command is valid only for PIM-SM.
The interval set by the register-suppression-timeout command must be larger than two times the interval set by the probe-interval (IPv4) command.
