Configuring Ipv4 Vrrp Packet Attributes - HP 5900 Series Configuration Manual

Configuration procedure
To configure the router priority, preemptive mode, and tracking function:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the priority of the
router in the VRRP group.
4. Enable the preemptive mode
for the router in a VRRP group
and configure the preemption
delay time.
5. Associate a VRRP group with
a 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 when the timer (3 x recorded interval + Skew_Time) expires, it regards the master as failed
and takes over as the new master.
Configuration procedure
To configure VRRP packet attributes:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the authentication
mode and authentication key
for an IPv4 VRRP group to
send and receive VRRP
packets.

Remarks

N/A
The default setting is 100.
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.
By default, a VRRP group is not
associated with any track entry.
Remarks

By default, authentication is
