HSRP Configuration | Hot Standby Router Protocol | CCNA 200-301

in this video I explained how to configuring, verifying and troubleshooting HSRP.
for configuring use this commands:
Router(config-if)# standby group ip ip-address
The interface must be on the same subnet as the other HSRP router or routers. The group number and virtual ip-address must be the same on all HSRP routers
nless the priority command is used, the first router configured becomes the HSRP active router.
Router(config-if)# standby group ip priority
Also, to make sure that a Router resumes the active
router role after losing connectivity, the standby preempt command is configured.
Router(config-if)# standby group ip preempt
to verifying HSRP:
The show standby brief command displays the most pertinent information you might need in a few lines of output. The more verbose show standby command provides additional information, such as the number of state changes, the virtual MAC address, hellos, and the group name.
For Troubleshooting HSRP issues:
 First The active router that controls the virtual IP address for the group was not successfully elected. Check the active router
 The HSRP routers are not connected to the same network segment. Routers must be the same network.
 The HSRP routers are not configured with the same virtual IPv4 address. Check the virtual IP address.
 The HSRP routers are not configured with the same HSRP group number. Check the HSRP group.
 And also End devices are not configured with the correct default gateway address. Check the computers default gateway.
