Disabling VSRP Backup Preemption

VSRP backup preemption prevents a Backup device with a higher priority from taking over as Master from another Backup that has a lower priority but has already become the Master of the VRID.

As a prerequisite, a VSRP session must be globally enabled using the router vsrp command in global configuration mode.

  1. Configure a VLAN by assigning an ID to the VLAN.
    device(config)# vlan 200
  2. Configure the interfaces on which VSRP service is to be enabled by adding ports to the VLAN.
    device(config-vlan-200)# tagged ethernet 1/1/1 to 1/1/8
  3. Assign a VSRP VRID to the VLAN.
    device(config-vlan-200)# vsrp vrid 200
  4. Disable preemption on a backup.
    device(config-vlan-200-vrid-200)# non-preempt-mode
