Step Command Remarks
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, H3C recommends you not to use 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 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,
change the IPv6 address of the interface on the IP address owner first and then remove the VRRP group
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.
To configure router priority, preemptive mode and interface tracking:
