Configuring Ipv4 Vrrp Packet Attributes - HP 6125XLG Configuration Manual

Step
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 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.
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.
4. Configure the interval at
which the master in an IPv4
VRRP group sends VRRP
advertisements.
5. Enable TTL check for IPv4
VRRP packets.

Remarks
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
N/A
N/A
By default, authentication is
disabled.
The default setting is 100
centiseconds.
To maintain system stability, HP
recommends that you set the VRRP
advertisement interval to be no less
than 100 centiseconds.
By default, TTL check for IPv4 VRRP
packets is enabled.
