HSRP change priority didn't failover

The Hot Standby Router Protocol (HSRP) is a commonly used protocol in network configurations. It provides redundancy and increases network reliability in the event of a router failure. The basic concept of HSRP is that two routers are configured to provide the same service, and each router is assigned a priority value. The router with the highest priority will be the active router, while the other router is in standby mode. HSRP provides a mechanism for quickly switching from one router to the other if the active router fails.

In order to change the priority of an HSRP router, it is necessary to edit the router configuration. This can be done either through a command line interface or through a graphical user interface, depending on the type of router being used. It is important to note that changing the priority of an HSRP router does not automatically cause a failover. The active router will remain active until it fails or until the standby router is manually configured to become the active router.

When changing the priority of an HSRP router, the priority value must be changed on both the active and standby routers. It is important to ensure that the priority values are set such that the correct router is the active router. If the priority values are not set correctly, it can result in the wrong router being active, which can lead to network instability.

Once the priority values have been changed, it is important to verify that the correct router is active. This can be done by pinging the virtual IP address that is configured for the HSRP router. If the active router is responding to the ping, then the priority change was successful. If the standby router is responding to the ping, then the priority change was not successful and the priority values must be adjusted.

In summary, HSRP is a protocol that is used to provide redundancy and increase network reliability. In order to change the priority of an HSRP router, it is necessary to edit the router configuration. Changing the priority of an HSRP router does not automatically cause a failover, and it is important to ensure that the priority values are set such that the correct router is the active router. Once the priority values have been changed, it is important to verify that the correct router is active by pinging the virtual IP address that is configured for the HSRP router.
