Configuring HSRP
HSRP and Switch Stacks
HSRP hello messages are generated by the stack master. If an HSRP-active stack master fails, a flap in
the HSRP active state might occur. This is because HSRP hello messages are not generated while a new
stack master is elected and initialized, and the standby router might become active after the stack master
fails.
