Caution:
You should configure this function before creating a standby group. Otherwise, you
cannot ping the virtual IPv6 addresses of standby groups.

1.3.3 Configuring the Association Between Virtual IPv6 Address and MAC Address

After the virtual IPv6 address of a standup group is associated with the MAC address,
the master switch 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 switch properly.
There are two types of association between virtual IPv6 address and MAC address:
Virtual IPv6 address is associated with virtual router MAC address
By default, a MAC address is created for a standby group after the standby 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 need not update the
association between IPv6 address and MAC address when the master switch changes.
Virtual IPv6 address is associated with real MAC address of the interface
When an IP address owner exists in a standby group, if 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 standby 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:
Enter system view
Configure the association
between virtual IPv6
address and MAC
address
To do...
system-view
vrrp ipv6 method
{ real-mac | virtual-mac }
Use the command...

Remarks
—
Optional
The virtual MAC address
of the standby group is
associated with the virtual
IPv6 address by default.
