Specify the type of the MAC addresses mapped to the virtual IPv6 addresses before creating a VRRP
group. Otherwise, you cannot change the type of the MAC addresses mapped to virtual IPv6
addresses.
To specify the type of MAC addresses mapped to virtual IPv6 addresses:

Optional.
Virtual MAC address by default.
Creating a VRRP group and configuring a virtual IPv6 address
When creating a VRRP group, configure a virtual IPv6 address for the VRRP group. You can configure
multiple virtual IPv6 addresses for a VRRP group.
A VRRP group is automatically created when you specify the first virtual IPv6 address for the VRRP
group. If you specify another virtual IPv6 address for the VRRP group later, the virtual IPv6 address is
added to the virtual IPv6 address list of the VRRP group.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IPv6 address on an interface, configure an
IPv6 address for the interface and make sure that it is in the same network segment as the virtual IPv6
address to be configured.
Configuration guidelines
 When a router is the IP address owner in a VRRP group, HP recommends not using 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 using 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 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.
 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.
