HSRP and Packer Tracer

[kevin ponzon]

Hi friends, i'm actually learning about HSRP protocol.

I need to know in packet tracer:

-How to reboot HSRP process in a HSRP group ?

-How to force one router to be an active router in a HSRP group ( i've already tried to change the priority but it's doesn't work) ?

-Why if i write that  Router(config-if)#standby 1 track Serial 0/1, and Serial 0/0 change status to down , it's doesn't decrease by ten the priority ?

There's my pkt file if you need.

Thanks for help.

-How to force one router to be an active router in a HSRP group ( i've already tried to change the priority but it's doesn't work)?

A: You can use el command standby 1 preetemp in the router you want to be the active. If you do not use the preempt standby command in the configuration of a router, that router will not become the active router, even if its priority is higher than that of the remaining routers.

-Why if i write that  Router(config-if)#standby 1 track Serial 0/1, and Serial 0/0 change status to down , it's doesn't decrease by ten the priority ?

A: No, the priority only changes when the interface Serial0/1 goes down and when goes back to up state, because this interface has the track Serial0/0 hasn't.

Thanks for your help ,

Actually i've changed the track for Serial 0/0 by command: Router(config-if)#standby 1 track Serial 0/0

and when Serial 0/0 goes down it's decrease by ten the priority !

but even with this decrease, the router stays like active router instead standby router !

Maybe i can fix that by restart hsrp process but i don't know how !

Have you added preempt on both routers as already suggested. Even if the standby router now has a higher priority it won't take over unless you have added that command to your HSRP configuration.

i'll try this.

I've forgot this input on this on both routers 

[Diana Karolina Rojas]

Hello Kevin!

What priority did you configure in your routers? are you using the default priority on both?

Hello anaid

Actually yes i've used the default priority on both routers.

Here is the simulation, corrected.

Hi, sorry i was travelling , i've not tested your corrected simulation,

today i've tried it but it doesn't works, because the file is incompatble with the last version of packet tracer, can you try to send again another simulation made with the last version of packet tracer please ?

Hello!

It's strange because I have the last version of packet tracer and I only modified your own simulation.

Here are the configuration of your routers (corrected):
