Virtual IPv6 address is associated with real MAC address of the interface
If an IP address owner exists in a VRRP group and you associate the virtual IPv6 address with the
virtual MAC address, two MAC addresses are associated with an IPv6 address. In this case, you can
associate the virtual IPv6 address of the VRRP group with the real MAC address, so that the packets
from a host is forwarded to the IP address owner according the real MAC address.
Follow these steps to configure the association between MAC address and virtual IPv6 address:

Use the command…

virtual-mac }
Optional
The virtual MAC address of the
VRRP group is associated with
the virtual IPv6 address by
default.
You should configure this function before creating a VRRP group. Otherwise, you cannot modify the
mapping between the virtual IPv6 address and the MAC address.
Creating VRRP Group and Configuring Virtual IPv6 Address
You need to configure a virtual IPv6 address for a VRRP group when creating the VRRP group. You can
configure multiple virtual IPv6 addresses for a VRRP group.
A VRRP group is created automatically 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.
It is not recommended to create VRRP groups on the VLAN interface of a super VLAN. Otherwise,
network performance may be affected.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IPv6 address, you should first configure an IPv6
address of the interface and ensure that the virtual IPv6 address to be configured is in the same network
segment as the IPv6 address of the interface.
