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 to 255 and the virtual-address is not equal to the interface’s primary IP address,
an error message appears.
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
priority
Enter a number as the priority. Enter 255 only if the router’s virtual address is the same as
the interface’s primary IP address (that is, the router is the OWNER).
Range: 1 to 255
Default: 100

Note: Configuring VRRP priority 255 on an interface on which DHCP Client is enabled is
not supported.
