Usage
Information
To guarantee that a VRRP group becomes MASTER, configure the VRRP group’s virtual address with
same IP address as the interface’s primary IP address and change the priority of the VRRP group to 255.
If you set the priority command to 255 and the virtual-address is not equal to the interface’s
primary IP address, an error message appears.
NOTE: Configuring VRRP priority 255 on an interface on which DHCP Client is enabled is not
supported.
