OS10 Enterprise Edition User Guide Release 10.4.0E(R3)


Disable preempt

Prevent the Backup router with the higher priority from becoming the master router by disabling the preemption process. The preempt command is enabled by default. The command forces the system to change the master router if another router with a higher priority comes online.

You must configure all virtual routers in the VRRP group with the same settings. Configure all routers with preempt enabled or configure all with preempt disabled.

  1. Create a virtual router for the interface with the VRRP identifier in INTERFACE mode (1 to 255).
  2. Prevent any backup router with a higher priority from becoming the Master router in INTERFACE-VRRP mode.
