Default

Group, 0; hello seconds, 1; hold seconds, 3

Description

This command allows you to change the hello and hold intervals for HSRP. If this router doesn’t hear from another router in this HSRP group for a period of hello-seconds, the other router is considered “down.” Once a router is declared “down,” it is considered down for a period of at least hold-seconds.
