Configuring Ipv6 Vrrp Packet Attributes; Disabling An Ipv6 Vrrp Group - HP MSR Series Configuration Manual

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 VRRP advertisement before the timer
(3 x recorded interval + Skew_Time) expires, it regards the master as failed and takes over.
• A high volume of network traffic might cause a backup to fail to receive VRRP advertisements from
the master within the specified time. As a result, an unexpected master switchover occurs. To solve
this problem, configure a larger interval.
Configuration procedure
To configure the IPv6 VRRP packet attribute:
Step
1. Enter system view.
Enter interface view.
2.
3. Set the IPv6 VRRP advertisement
interval.
4. Return to system view.
5. Set a DSCP value for IPv6 VRRP
packets.

Disabling an IPv6 VRRP group

You can temporarily disable an IPv6 VRRP group. After being disabled, the VRRP group stays in
initialized state, and its configurations remain unchanged. You can change the configuration of a VRRP
group when it is disabled. Your changes take effect when you enable the VRRP group again.
To disable an IPv6 VRRP group:
Step
1. Enter system view.
2. Enter interface view.

N/A
The default setting is 100
centiseconds.
To maintain system stability, HP
recommends that you set the VRRP
advertisement interval to be
greater than 100 centiseconds.
N/A
The DSCP value identifies the
packet priority during
transmission.
By default, the DSCP value for
IPv6 VRRP packets is 56.
