What is HSRP?
Its meaning is Hot Standby Router Protocol, which is a protocol that Cisco first developed and its function is to provide an alternative or back-up Gateway to the network in case of any problem with the router.

As we see in Tablouji, the PC3 computer has three ways to reach the target, which is here R4, and of course we will select the GateWay for the device ourselves to use one of the three existing routers, and I have chosen Router 1 to be the default Router for the network, but the question now is what if the Router stopped one from What will happen? The answer, of course, is that the whole network will stop working, hence the HSRP idea
The idea of ​​the HSRP is to provide more than one way for the network to reach the goal by giving the three existing routers IPI and Mac Address Id and one will be the default GateWay and if the second router is broken then the number 3 will pass the traffic to R4 and of course all this is done without the user feeling In anything, in other words, this technique creates an imaginary router that has one port, which is the gateway to the network, and of course this port has IP and Mac I study the user understands it is the gateway to the network, but in fact it is three routers, one of which supervises the traffic pass even if in the event of a problem in this Router This technology automatically converts traffic to the second one, and so on
Method of numbers
Before I start the way of setting up routers, I would like to notice that the computer in the tabloji has IP 192.168.1.2/24 and gateway 192.168.1.1 and now we go to the router number one and go to the port connected to the network and here is Ethernet 0/0 and we do the following


interface Ethernet0 / 0
ip address 192.168.1.4 255.255.255.0
no shutdown
standby 1 priority 90
standby 1 ip 192.168.1.1
And the process of transferring from one router to another is done by sending a hello message between the routers in the group. We can also monitor the second output of the router that communicates with the router 4 by monitoring the port status is it UP or Down because if it fails it will also stop working on the network so we also resort to Monitor it by adding the following command

standby 1 track Ethernet 0/2
As a form of security, put a password between the routers in the group with the following command

standby 1 authentication password
And of course we put a password in the place of Password and to display the protocol status on the router we use the show standby command and I hope you notice the word Active, which means that this router is the one that passes the data while the word standby denotes the router is the second in the list of preference or the first reserve and the word listen indicates The second reserve

Now let's do a trace from the device on the network to see with which outlets the device is connected and shown in the picture

And we see that reaching the goal is through the IP 192.168.1.3 which is the first routine. To make sure of the matter, close the port on the first router and do the tracking process to see that the IP will switch to IP 192.168.1.4, which is the second router.
Another word as I explained that this protocol Cisco developed it so it will only work on its devices and to apply this command to other routers we resort to another protocol called VRRP which performs the same process and is valid for all types of routers
