To do… Use the command… Remarks
Configure the association
between virtual IPv6 address
and MAC address
vrrp ipv6 method { real-mac |
virtual-mac }
Optional
The virtual MAC address of the
VRRP group is associated with
the virtual IPv6 address by
default.
z
When VRRP works in the load balancing mode, the association between virtual IPv6 address and
the MAC address cannot be configured. In this mode, the virtual IPv6 address is always associated
with the virtual MAC address.
z
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.
Configuration procedure
Follow these steps to create VRRP group and configure its virtual IPv6 address:
