Hi Expert,
We have implemented hsrp in our networ. We are using HSRP tracking functionality ( tracking serial interface). I want to know how much time standy router take to get active state when serial link get down.
Thanks in advance.

Hi,
Have a look at this Q&A
A. Yes, the standby router takes over once the holdtime expires. By default, this is equivalent to three hello packets from the active router having been missed. The actual convergence time depends on the HSRP timers configured for the group and possibly on routing protocol convergence. The HSRP hellotime timer defaults to three and the holdtime timer defaults to ten
