Parameters
dscp-value
: Specifies a DSCP value for IPv6 VRRP packets, in the range of 0 to 63. The default is
56.
Usage guidelines
The DSCP value identifies the packet priority during transmission. A greater DSCP value means a
higher packet priority.
Examples
# Configure the DSCP value for IPv6 VRRP packets as 30.

[Sysname] vrrp ipv6 dscp 30
vrrp ipv6 vrid preempt-mode

Parameters
virtual-router-id
: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
delay
delay-value
: Specifies a preemption delay time in the range of 0 to 255 in seconds. The default
setting is 0 seconds.
Usage guidelines
In non-preemptive mode, when a router in the IPv6 VRRP group becomes the master, it acts as the
master as long as it operates correctly, even if a backup is assigned a higher priority later. The
non-preemptive mode helps avoid frequent switchover between the master and backups.
