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 on an interface, configure
an IPv6 address for the interface and ensure that it is in the same network segment as the
virtual IPv6 address to be configured.
Configuration procedure
Follow these steps to create a VRRP group and configure its virtual IPv6 address:
To do… Use the command… Remarks
Enter system view system-view —
Enter the specified interface
view
interface interface-type
interface-number
—
Create a VRRP group and
configure its virtual IPv6
address, which is a link local
address
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address
link-local
Required
No VRRP group is created by
default.
The first virtual IPv6 address of
the VRRP group must be a link
local address. Only one link
local address is allowed in a
VRRP group, and must be
removed the last.
Configure the VRRP group with
a virtual IPv6 address, which is
a global unicast address
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address
Optional
By default, no global unicast
address is configured as the
virtual IPv6 address of a VRRP
group.
z A VRRP group is removed after you remove all the virtual IPv6 addresses in it. In addition,
configurations on that VRRP group do not take effect any longer.
z Removal of the VRRP group on the IP address owner causes IP address collision. To
resolve the collision, it is recommended to change the IPv6 address of the interface on the
IP address owner first and then remove the VRRP group from the interface.
