- Tracy Yang (Unlicensed)
The set protocols vrrp interface vrid preempt enable command configures the preemptive mode of the device in a VRRP group.
NOTE: This command applies to both VRRPv2 and VRRPv3 configuration. |
Command Syntax
set protocols vrrp interface <interface-name> vrid <virtual-router-id> preempt enable <true | false>
Parameter
Parameter | Description |
interface <interface-name> | Specifies the Layer 3 interface name of VRRP device. The value could be the VLAN interface name, the routed interface or the sub-interface name. The value is a string. |
vrid <virtual-router-id> | Specifies the VRID of a VRRP group. The value is an integer that ranges from 1 to 254. |
preempt enable <true | false> | Enables or disables the preemptive mode of the device. The value could be true or false.
By default, preemptive mode is enabled. |
Usage Guidelines
To enable the device with higher priority in a VRRP group to be the master, set the preemptive mode on the device.
For the backup device, if it has a higher priority than the master, the working mode of the backup (preemptive or non-preemptive) determines whether the master is re-selected.
- Preemptive mode: If the priority of the backup router is higher than the priority of the current master router, the backup router automatically becomes the master router.
- Non-preemptive mode: As long as the master router is working properly, the backup router with a higher priority cannot become the master router.
By default, the preemptive mode is enabled, therefore, the device with a high priority is the master of the VRRP group.
NOTE: The IP address owner always works in preemptive mode, regardless of whether the preemption function is enabled or not. |
Example
- Enable the preemptive mode of the device in a VRRP group.
