Creating a VRRP Group and Configuring Virtual IPv6 Address
When creating a VRRP group, configure a virtual IPv6 address for the VRRP group. You can configure
multiple virtual IPv6 addresses for a VRRP group.
A VRRP group is automatically created 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.
NOTE:
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
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.
NOTE:
•
When VRRP works in load balancing mode, the virtual IPv6 address of a VRRP group cannot be the
same as the IPv6 address of any interface in the VRRP group. In other words, a VRRP group does not
have an IP address owner in load balancing mode.
• 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.
• 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.
