Step Command Remarks
81. Create a VRRP group and
configure its virtual IPv6
address, which is a link local
address.
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address link-local
No VRRP group is created by
default.
The first virtual IPv6 address of the
VRRP group must be a link local
address. Only one link local
address is allowed in a VRRP
group, and must be removed the
last.
82. Configure the VRRP group
with a virtual IPv6 address,
which is a global unicast
address.
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address
Optional.
By default, no global unicast
address is configured as the virtual
IPv6 address of a VRRP group.
Configuring router priority, preemptive mode, and tracking
function
Configuration prerequisites
Before you configure router priority, preemptive mode and tracking function, create a VRRP group and
configure its virtual IPv6 address.
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.
• Interface tracking is not configurable on an IP address owner.
• If you configure an interface to be tracked or a track entry to be monitored on a router that is the IP
address owner in a VRRP group, the configuration does not take effect. If the router is not the IP
address owner in the VRRP group later, the configuration takes effect.
• The tracked interface can be a Layer 3 Ethernet interface, a VLAN interfaces, a
synchronous/asynchronous serial interface, a POS interface, an MP-group interface, or an HDLC
link bundle interface. The Layer 2 protocol used by the tracked synchronous/asynchronous serial
interfaces can be PPP only, and the tracked synchronous/asynchronous serial interfaces cannot be
added to a virtual template or MP-group.
• If the state of a tracked interface changes from down or removed to up, the priority of the router that
owns the interface is automatically restored.
• If the state of a track entry changes from negative or invalid to positive, the priority of the router
where the track entry is configured is automatically restored.
Configuration procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, determine which
router in the VRRP group serves as the master.
To configure router priority, preemptive mode and interface tracking:
