Configuring the Association Between Virtual IPv6 Address and MAC Address

After the virtual IPv6 address of a VRRP group is associated with the MAC address, the master takes
the configured MAC address as the source MAC address of the packets to be sent, so that the hosts in
the internal network can learn the association between the IPv6 address and the MAC address and thus
forward the packets to be forwarded to the other network segments to the master.
There are two types of association between virtual IPv6 address and MAC address:
Virtual IPv6 address is associated with virtual MAC address
By default, a MAC address is created for a VRRP group after the VRRP group is created, and the virtual
IPv6 address is associated with the virtual MAC address. With such association adopted, the hosts in
the internal network do not need to update the association between IPv6 address and MAC address
when the master changes.
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:

Optional
When VRRP works in the load balancing
mode, the association between the virtual IP
address and the MAC address can be
configured but is not effective.
