Creating A Vrrp Group And Configuring A Virtual Ipv6 Address - HPE FlexNetwork HSR6800 series Configuration Manual

Creating a VRRP group and configuring 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
•
When a router is the IP address owner in a VRRP group, Hewlett Packard Enterprise
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 using
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.
•
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.
Configuration procedure
To create a VRRP group and configure its virtual IPv6 address:
Step
1. Enter system view.
2. Enter the specified interface
view.
3. Create a VRRP group and
configure its virtual IPv6
address, which is a link local
address.
4. Configure the VRRP group
with a virtual IPv6 address,
which is a global unicast
address.

Remarks
N/A
N/A
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.
Optional.
By default, no global unicast
address is configured as the
virtual IPv6 address of a VRRP
group.
