VRRP 1 was configured with IP address "10.10.10.1" as the "Master" IP address and "10.10.10.2" as the "Slave" IP address. For this topology, the following values are recommended: The master controller is configured for a number of VRRP instances (equal to the number of local controllers the master is backing up). HSRP (Hot Standby Router Protocol) is the Cisco proprietary protocol for providing redundancy in router networks. VRRP Configuration Examples. << If your deployment includes a VRRP master with preemption disabled and an uplink switch is running RSTP, a higher value will prevent the VRRP master from regaining the master state after it reboots.

If you do not want to dedicate a switch to be a VRRP backup (and therefore leave it idle unless the primary fails), you can create a load-sharing configuration in which each participating switch simultaneously acts as a primary and a backup.
