Configuration guidelines
• 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 Network
Management Command Reference.
• When VRRP operates 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.
• You can configure a maximum of 16 VRRP groups on an interface and a maximum of 16 virtual IPv6
addresses in a VRRP group.
• 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.
Configuration procedure
To create a VRRP group and configure its virtual IPv6 address:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter the specified interface
view. interface interface-type
interface-number
N/A
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.
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.
