The VRRP priority range is 1-254 (a bigger number<br />

indicates a higher priority). The router with higher<br />

priority will be more likely to become the gateway router.<br />

Heartbeat package transmission time interval between<br />

routers in the virtual ip group. Range: 1-255.<br />

If the router works in the preemption mode, once it finds<br />

that its own priority is higher than that of the current<br />

gateway router, it will send VRRP notification package,<br />

resulting in re-election of gateway router and eventually<br />

replacing the original gateway router. Accordingly, the<br />

original gateway router will become a Backup router.<br />
