What is preempt in HSRP?

The standby preempt command enables the Hot Standby Router Protocol (HSRP) router with the highest priority to immediately become the active router. This means that another HSRP router with higher priority can become the active router if that router has standby preempt enabled.

What is preempt mode?

You can configure VRRP to preempt the existing router. This means that if a new VRRP router is added to the network with priority higher than the existing routers, then the new router becomes the master. If preemption is disabled, then the new router will not become a master.

Can 2 HSRP routers become active active?

What is VRRP priority?

The VRRP priority must express how efficiently a VRRP router would perform as a backup to a virtual router defined in the VRRP router. If there are multiple backup VRRP routers for the virtual router, the priority determines which backup VRRP router is assigned as master if the current master fails.

What is the default HSRP priority?

100
The default HSRP priority is 100. If you want an HSRP router to be elected as the active router, you should set the priority to a value higher than the default of 100.

Can we do load balancing in HSRP?

Its major advantage is its ability to automatically support load-balancing of multiple uplinks. HSRP and VRRP only have one router active at any time, per group. In order to take advantage of all links at all times, you have to configure multiple groups.
