To avoid frequent state changes among members in a VRRP group and to provide the backups enough time to collect information (such as routing information), a backup does not immediately become the master after it receives an advertisement with lower priority than the local priority. Instead, it waits for a period of time before taking over as the master. Examples # Enable the preemptive mode for VRRP group 1, and set the preemption delay time to 5 seconds. system-view [Sysname] interface vlan-interface 2 [Sysname-Vlan-interface2] vrrp ipv6 vrid 10 preempt-mode delay 5 Related commands display vrrp ipv6 vrrp ipv6 vrid priority Use vrrp ipv6 vrid priority to configure the priority of the router in an IPv6 VRRP group.

A router with a higher priority is more likely to become the master. VRRP priority is in the range of 0 to 255, and a greater number represents a higher priority. Priorities 1 to 254 are configurable. Priority 0 is reserved for special uses, and priority 255 is for the IP address owner. The router acting as the IP address owner in a VRRP group always has a running priority of 255 and acts as the master as long as it operates properly.

Parameters
virtual-router-id
: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
priority-value
: Specifies a priority value in the range of 1 to 254. A higher number indicates a higher
priority.
Usage guidelines
VRRP determines the role (master or backup) of each router in a VRRP group by priority. A router with a
higher priority is more likely to become the master.
VRRP priority is in the range of 0 to 255, and a greater number represents a higher priority. Priorities 1
to 254 are configurable. Priority 0 is reserved for special uses, and priority 255 is for the IP address
owner. The router acting as the IP address owner in a VRRP group always has a running priority of 255
and acts as the master as long as it operates properly.
Examples
# Configure the priority of the device in VRRP group 1 on VLAN-interface 2 as 150.
