2.

Enter interface view.

interface interface-type

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 seconds, which means an

immediate preemption.

5.

Associate a VRRP group with
a track entry.

vrrp vrid virtual-router-id track
track-entry-number [ reduced

priority-reduced | switchover ]

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 VRRPv3, authentication mode and authentication key settings do not take effect.

In VRRPv2, all routers in a VRRP group must have the same VRRP advertisement interval.

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 when the timer (3 x recorded interval + Skew_Time) expires, it regards the master as failed
and takes over as the new master.
