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 procedure
To create a VRRP group and configure its virtual IPv6 address:
Ste
p
Command Remarks
1. Enter system view. system-view N/A
2. Enter the specified interface
view.
interface interface-type
interface-number
N/A
3. 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
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.
4. 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.
NOTE:
• When a router is the IP address owner in a VRRP group, HP recommends you not to use the IPv6 address
of the interface (virtual IPv6 address of the VRRP group) to establish an OSPFv3 nei
g
hbor relationship
with the adjacent router, that is, not to use the ospfv3 area command to enable OSPFv3 on the
interface.
• You can create up to 16 VRRP groups on an interface and up to 16 virtual IPv6 addresses in a VRRP
group.
• A VRRP group is removed after you remove all the virtual IPv6 addresses in it. In addition, confi
g
urations
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
g
roup
from the interface.
Configuring router priority, preemptive mode and tracking
function
Configuration prerequisites
Before you configure router priority, preemptive mode and tracking function, create a VRRP group and
configure its virtual IPv6 address.
Configuration procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, determine which
router in the VRRP group serves as the master.
