Configuring Router Priority, Preemptive Mode And Tracking Function - H3C S9500E Series Configuration Manual

When VRRP works in load balancing mode, the virtual IPv6 address cannot be the same as the IPv6
•
address of any interface in the VRRP group. In other words, in load balancing mode, the VRRP group
does not have an IP address owner.
Up to 16 VRRP groups can be created on an interface and up to 16 virtual IPv6 addresses can be
•
assigned to a VRRP group.
A VRRP group is removed after you remove all virtual IPv6 addresses in it. In addition, configurations on
•
that VRRP group no longer take effect.
Removal of the VRRP group of the IP address owner will cause IP address collision. In such a case, H3C
•
recommends that you change the IPv6 address of the interface of the IP address owner to resolve the
collision.
Configuring router priority, preemptive mode and tracking
function
Configuration prerequisites
Before configuring these features, you should first create a VRRP group and configure a virtual
IPv6 address.
Configuration procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, you can
decide which router in the VRRP group serves as the master.
To configure router priority, preemptive mode and interface tracking:
To do...
1. Enter system view
2. Enter the specified interface
view
3. Configure the priority of the
router in the VRRP group
4. Configure the router in the
VRRP group to work in
preemptive mode and
configure preemption delay of
the VRRP group
5. Configure the interface to be
tracked
6. Configure VRRP to track a
specified track entry
Use the command...
system-view
interface interface-type interface-
number
vrrp ipv6 vrid virtual-router-id
priority priority-value
vrrp ipv6 vrid virtual-router-id
preempt-mode [ timer delay
