R0106-HP MSR Router Series High Availability Command Reference(V7)

48
Parameters
virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
Usage guidelines
You can use this command to temporarily disable an IPv6 VRRP group. After this command is configured,
the VRRP group stays in initialized state, and its configurations remain unchanged. You can change its
configuration, and your changes take effect when you enable the VRRP group again.
Examples
# Disable IPv6 VRRP group 1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] vrrp ipv6 vrid 1 shutdown
vrrp ipv6 vrid timer advertise
Use vrrp ipv6 vrid timer advertise to configure the interval at which the master in an IPv6 VRRP group
sends VRRP advertisements.
Use undo vrrp ipv6 vrid timer advertise to restore the default.
Syntax
vrrp ipv6 vrid virtual-router-id timer advertise adver-interval
undo vrrp ipv6 vrid virtual-router-id timer advertise
Default
The master in an IPv6 VRRP group sends VRRP advertisements at an interval of 100 centiseconds.

Parameters
virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
adver-interval: Specifies an interval for the master in the specified IPv6 VRRP group to send VRRP
advertisements, in the range of 100 to 4095 centiseconds.
Usage guidelines
The master in an IPv6 VRRP group periodically sends VRRP advertisements to declare its presence. You
can use this command to configure the interval at which the master sends VRRP advertisements.
HP recommends that you set the VRRP advertisement interval to be greater than 100 centiseconds to
maintain system stability.
The routers in an IPv6 VRRP group can have different intervals for sending VRRP advertisements. The
master in the VRRP group sends VRRP advertisements at the specified interval and carries the interval
attribute 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 × VRRP advertisement sending interval + Skew_Time) expires, it regards the master as failed and takes
over as the master.
