Above we can see that SW2 is seeing Eventually it ends up in the standby state. By default the switch with the highest priority will become the active HSRP device. If the priority is the same then the highest IP address will be the tie-breaker. Even though SW2 has a higher priority, SW1 remains the active router. Another useful command to verify which router is active or standby is the show standby brief command:.

When we enable preemption the switch with the highest priority or IP address in case the priority is the same will always become the new active device. By default preemption will take effect immediately but it might be a good idea to use a delay.
If you want to add a delay then you can do it like this:. HSRP also supports authentication.

You can choose between plaintext or MD5 authentication. This ensures that all packets sent between the two switches are authenticated. This prevents someone on the By default HSRP is pretty slow. We can speed things up by changing the timers with the standby timers command. Make sure your hold time is at least three times the hello timer. You can change the version by using the standby version command. Take a look at the following picture:.
When this happens it will send an ICMP redirect to the computer.

HSRP offers a feature called interface tracking. We can select an interface to track and if it fails we will give it a penalty. This way your priority will decrease and another device can become the active router. Make sure you have enabled preemption if you want to use interface tracking.
When the line-protocol changes goes down then the object state will change. What's new in Packet Tracer 7.
