Configuring IPv6 VRRP packet attributes
This section describes how to configure IPv6 VRRP packet attributes.
Configuration guidelines
• 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 before the timer (3 x recorded interval + Skew_Time)
expires, it regards the master as failed and takes over as the new master.
• A high volume of network traffic might cause a backup to fail to receive VRRP advertisements
from the master within the specified time, resulting in an unexpected master switchover. To
solve this problem, configure a larger interval.
Configuration procedure
To configure the IPv6 VRRP packet attribute:
Step Command Remarks
1. Enter system view.

2. Enter interface view.

N/A
3. Configure the IPv6 VRRP
advertisement interval.
vrrp ipv6 vrid
virtual-router-id
timer
advertise
adver-interval
The default setting is 100
centiseconds.
As a best practice to maintain
system stability, set the VRRP
advertisement interval to be
greater than 100 centiseconds.
4. Return to system view.

5. Configure a DSCP value for
IPv6 VRRP packets.
vrrp ipv6 dscp
dscp-value
The DSCP value identifies the
packet priority during
transmission.
By default, the DSCP value for
IPv6 VRRP packets is 56.
