Creating a VRRP group and assigning a 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.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IPv6 address on an interface, configure an IPv6
address for the interface and make sure that it is in the same network segment as the virtual IPv6 address
to be configured.
Configuration guidelines
•
Do not create VRRP groups in the VLAN interface of a super VLAN. Otherwise, network
performance might be affected.
•
When a router is the IP address owner in a VRRP group, H3C recommends not using the IPv6
address of the interface (virtual IPv6 address of the VRRP group) to establish an OSPFv3 neighbor
relationship with the adjacent router, that is, not to use the ospfv3 area command to enable
OSPFv3 on the interface. For more information about ospfv3 area command, see Layer 3—IP
Routing Command Reference.
•
When VRRP operates 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.
•
The maximum number of VRRP groups on an interface is 16 and varies with device model and
interface cards. The maximum number of virtual IPv6 addresses in a VRRP group is 10.
•
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, change the IPv6 address of the interface on the IP address owner first and then remove the
VRRP group from the interface.
