Configuration guidelines
• The running priority of an IP address owner is always 255, and you do not need to configure it.
An IP address owner always operates in preemptive mode.
• If you configure the vrrp vrid track priority reduced or vrrp vrid track switchover command
on an IP address owner, the configuration does not take effect until the router becomes a non IP
address owner.
Configuration procedure
To configure the router priority, preemptive mode, and tracking function:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface
interface-type
interface-number
N/A
3. Configure the priority of the
router in the VRRP group.
vrrp vrid
virtual-router-id
priority
priority-value
The default setting is 100.
4. Enable the preemptive mode
for the router in a VRRP
group and configure the
preemption delay time.
vrrp vrid
virtual-router-id
preempt-mode
[
delay
delay-value ]
By default, the router in a VRRP
group operates in preemptive
mode and the preemption delay
time is 0 centiseconds.
5. Associate a VRRP group
with a track entry.
vrrp vrid
virtual-router-id
track
track-entry-number
{
forwarder-switchover
member-ip
ip-address |
priority
reduced
[ priority-reduced ] |
switchover
|
weight reduced
[ weight-reduced ] }
By default, a VRRP group is not
associated with any track entry.
Configuring IPv4 VRRP packet attributes
Configuration guidelines
• You can configure different authentication modes and authentication keys for VRRP groups on
an interface. However, members of the same VRRP group must use the same authentication
mode and authentication key.
• In VRRPv2, all routers in a VRRP group must have the same VRRP advertisement interval.
• In VRRPv3, authentication mode and authentication key settings do not take effect.
• In VRRPv3, routers in an IPv4 VRRP group can have different intervals for sending VRRP
advertisements. The master in the VRRP group sends VRRP advertisements at specified
intervals, and carries the interval in the advertisements. After a backup receives the
advertisement, it records the interval in the advertisement. If the backup does not receive a new
VRRP advertisement from the master before the timer (3 x recorded interval + Skew_Time)
expires, it regards the master as failed and takes over as the new master.
