vrrp ipv6 vrid priority

Page 131 highlights

If you set the router in the VRRP group to operate in non-preemptive mode, the delay period automatically changes to zero seconds. To avoid frequent member state changes in a VRRP group and make the backups have enough time to collect information (such as routing information), each backup waits for a period of time (the preemption delay time) after it receives an advertisement with the priority lower than the local priority, then sends VRRP advertisements to start a new master election in the VRRP group and becomes the master. Before executing the command, create a VRRP group on an interface and configure the virtual IPv6 address of the VRRP group. Related commands: display vrrp ipv6.

A higher number indicates a higher priority. Description Use vrrp ipv6 vrid priority to configure the priority of the router in the specified VRRP group. Use undo vrrp ipv6 vrid priority to restore the default. By default, the priority of a router in a VRRP group is 100. Before executing the command, create a VRRP group on an interface and configure the virtual IPv6 address of the VRRP group. The role that a router plays in a VRRP group depends on its priority. A higher priority means that the router is more likely to become the master. Priority 0 is reserved for special use and 255 for the IP address owner. If the router is the IP address owner, its priority is always 255. Therefore, it remains as the master as long as it is functioning normally. Related commands: display vrrp ipv6. 126

If you set the router in the VRRP group to operate in non-preemptive mode, the delay period automatically
changes to zero seconds.
To avoid frequent member state changes in a VRRP group and make the backups have enough time to
collect information (such as routing information), each backup waits for a period of time (the preemption
delay time) after it receives an advertisement with the priority lower than the local priority, then sends
VRRP advertisements to start a new master election in the VRRP group and becomes the master.
Before executing the command, create a VRRP group on an interface and configure the virtual IPv6
address of the VRRP group.

Parameters
virtual-router-id
: VRRP group number, which ranges from 1 to 255.
priority-value
: Priority value of the router in the specified VRRP group, which ranges from 1 to 254. A
higher number indicates a higher priority.
Description
Use
vrrp ipv6 vrid priority
to configure the priority of the router in the specified VRRP group.
Use
undo vrrp ipv6 vrid priority
to restore the default.
By default, the priority of a router in a VRRP group is 100.
Before executing the command, create a VRRP group on an interface and configure the virtual IPv6
address of the VRRP group.
The role that a router plays in a VRRP group depends on its priority. A higher priority means that the
router is more likely to become the master. Priority 0 is reserved for special use and 255 for the IP address
owner.
If the router is the IP address owner, its priority is always 255. Therefore, it remains as the master as long
as it is functioning normally.
