3. Create a VRRP group and
assign a virtual IPv6 address,
which is a link-local address.
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address link-local
By default, no VRRP group exists.
The first virtual IPv6 address that
you assign to an IPv6 VRRP group
must be a link-local address, and it
must be the last address you
remove. Only one link local
address is allowed in a VRRP
group.
4. (Optional.) Assign a virtual
IPv6 address, which is a
global unicast address.
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address
By default, no global unicast
address is assigned for an IPv6
VRRP group.
Configuring the router priority, preemptive mode, and tracking
function
Configuration guidelines
• The running priority of an IP address owner is always 255, and you do not need to configure it. An
IP address owner always operates in preemptive mode.
• If you associate a track entry with a VRRP group on an IP address owner, the association does not
take effect until the router becomes a non-IP address owner.
• When the track entry changes from Negative to Positive or Notready, the router automatically
restores its priority.
Configuration procedure
To configure the router priority, preemptive mode, and tracking function:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the priority of the
router in the VRRP group.
vrrp ipv6 vrid virtual-router-id
priority priority-value
The default setting is 100.
4. Enable the preemptive mode
for the router in a VRRP group
and configure the preemption
delay time.
vrrp ipv6 vrid virtual-router-id
preempt-mode [ delay
delay-value ]
By default, the router in a VRRP
group operates in preemptive
mode and the preemption delay
time is 0 seconds, which means an
immediate preemption.
5. Associate a VRRP group with
a track entry.
vrrp ipv6 vrid virtual-router-id track
track-entry-number [ reduced
priority-reduced | switchover ]
By default, a VRRP group is not
associated with any track entry.
