Which value is used to determine the active router in an HSRP default configuration?

Q.

If there is no priority configured for a standby group, what determines which router is active? A.

The priority field is used to elect the active router and the standby router for the specific group.

In the case of an equal priority, the router with the highest IP address for the respective group is elected as active.

Furthermore, if there are more than two routers in the group, the second highest IP address determines the standby router and the other router/routers are in the listen state.

In an HSRP (Hot Standby Router Protocol) default configuration, the router priority value is used to determine the active router.

HSRP is a protocol that enables a group of routers to work together to present the appearance of a single virtual router to the hosts on a LAN (Local Area Network). This virtual router has a virtual IP address that can be used as the default gateway for hosts on the LAN.

When HSRP is enabled on a group of routers, one router is elected as the active router, and the others are in standby mode. The active router is responsible for forwarding packets sent to the virtual IP address, while the standby routers monitor the active router and take over if it fails.

The router priority value is used to determine which router will be the active router. By default, the router with the highest priority value will become the active router. If two or more routers have the same priority value, the router with the highest IP address on the HSRP interface will become the active router.

Therefore, in the default HSRP configuration, the router priority value is the most important factor in determining the active router. The router loopback address and IP address are not used for this purpose. The router tracking number is used to track the status of an interface, but it does not determine the active router in the default HSRP configuration.
