Configuring EX-switch to disable VRRP preempt.

Configuring EX switch to disable VRRP preempt.

Apply the below mentioned command to disable VRRP preemption on EX switches.

root@sw1# set interfaces vlan.10 family inet address 10.10.10.3/24 vrrp-group 10 virtual-address 10.10.10.1 priority 200 no-preempt accept-data

root@sw1# show interfaces vlan.10
family inet {
    address 10.10.10.1/24 {
       vrrp-group 10 {
          virtual-address 10.10.10.3;
          priority 200;
          no-preempt;
          accept-data;
        }
    }
}

Impact of disabling VRRP preemption :

> If you increase the priority of the Backup router, when the Primary router is present, the VRRP backup router will NOT become the primary router.

> If the VRRP preemption is disabled on VRRP Primary router, and if the VRRP Primary is rebooted, the VRRP backup router becomes VRRP Primary router. When the old VRRP Primary router comes back, it will NOT become VRRP Primary (even though it has higher priority as compared to the new VRRP Primary Router) and will remain VRRP backup router.
