Step Command

Remarks

3.

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.

4.

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.

NOTE:

When a router is the IP address owner in a VRRP group, H3C recommends you not to use the IPv6
address of the interface (virtual IPv6 address of the VRRP group) to establish an OSPFv3 neighbor

relationship with the adjacent router, that is, not to use the ospfv3 area command to enable OSPFv3 on

the interface. For more information about ospfv3 area command, see

Layer 3—IP Routing Command

Reference.

When VRRP works in load balancing mode, the virtual IPv6 address of a VRRP group cannot be the
same as the IPv6 address of any interface in the VRRP group. In other words, a VRRP group does not

have an IP address owner in load balancing mode.

A VRRP group is removed after you remove all the virtual IPv6 addresses in it. In addition, configurations
on that VRRP group do not take effect any longer.

Removal of the VRRP group on the IP address owner causes IP address collision. To resolve the collision,
change the IPv6 address of the interface on the IP address owner first and then remove the VRRP group

from the interface.

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 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:
