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

virtual IP address by
default.
Caution:
You should configure this function before creating a standby group. Otherwise, you
cannot modify the mapping between the virtual IP address and the MAC address.
1.2.4 Creating Standby Group and Configuring Virtual IP Address
You need to configure a virtual IP address for a standby group when creating the
standby group. A VRRP standby group is created automatically when you specify the
first virtual IP address for the standby group. If you specify a virtual IP address for the
standby group later, the virtual IP address is only added to the virtual IP address list of
the VRRP standby group.
I. Configuration prerequisites
Before creating standby group and configuring virtual IP address, you should first
configure the IP address of the interface and ensure that the virtual IP address to be
configured is in the same network segment as the IP address of the interface.
II. Configuration procedure
Follow these steps to create standby group and configure virtual IP address:
