If the outside link of the active router goes down, the standby router will take over and
become the active router. There is a default priority of 100 on routers configured with an
HSRP interface, and if you raise this priority (we’ll do this in a minute), it means your router
has a higher priority to become the active router. The reason I am bringing this up now is
because when a tracked interface goes down, it decrements the priority of this router.
