If you want to have the ability to share the IP address of the Master’s Interface, you would need to use the VRRP for that. VRRP stands for Virtual Router Redundancy Protocol. This can help provide the redundancy that is sometimes needed by the network.
The HSRP is also a type of redundancy protocol but it can be configured to work with a set of routers. This will make sure that it will only show one virtual router to the hosts of the LAN. Take note that HSRP already comes with different versions that are known to work. All the routers will have just one MAC address and also one IP address.
VRRP stands for Virtual Router Redundancy Protocol. This means that this will be in charge of providing redundancy to the network. HSRP is also a redundancy protocol, but Cisco creates this. This will make sure that any additional configuration on the devices that are all part of the subnet.
When the HSRP is being used, it will show that there is only one virtual router that is available. If these two will be checked by the different devices that are available in the network, there will be no difference between the two because this will make sure that the IP address will be the same in a group.
