ONFIGURATION
A standby group is removed after you remove all the virtual IPv6 addresses in it.
■
In addition, configurations on that standby group no longer take effect.
Configuration prerequisites
Before configuring these features, you should first create the standby group and
configure the virtual IPv6 address.
Configuration procedure
By configuring router priority, preemption mode and interface tracking, you can
decide which router in the standby group serves as the Master.
Follow these steps to configure router priority, preemption mode and interface
tracking:
To do...
Enter system view
Enter the specified interface
view
Configure the priority of the
router in the standby group
Configure the router in the
standby to work in
preemption mode and
configure preemption delay of
the standby group
Configure the interface to be
tracked
c
CAUTION:
The priority of an IP address owner is always 255 and not configurable.
■
Interface tracking is not configurable on an IP address owner.
■
Tracked interfaces can only be Layer 3 Ethernet interfaces, VLAN interfaces,
■
synchronous/asynchronous serial interfaces, or MP-group interfaces.
The priority of a device is reset if the state of the interface under tracking
■
changes from down to up.
Configuration prerequisites
Before configuring the relevant attributes of VRRP packets, you should first create
the standby group and configure the virtual IPv6 address.
Configuration procedure
Follow these steps to configure VRRP packet attributes:
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 delay-value ]
vrrp ipv6 vrid
virtual-router-id track
interface interface-type
interface-number [ reduced
priority-reduced ]
Remarks

-
Optional
100 by default
Optional
The router in the standby
group works in preemption
mode and the preemption
delay is zero seconds by
default.
Optional
No interface is being tracked
by default.
