Configuring Vrrp Packet Attributes - HP A5830 series Configuration Manual

To do...
• Configure VRRP to track a
specified track entry
The running priority of an IP address owner is always 255 and you do not need to configure it. An IP
address owner always works in preemptive mode.
Interface tracking is not configurable on an IP address owner.
If you configure an interface to be tracked or a track entry to be monitored on a router that is the IP
address owner in a VRRP group, the configuration does not take effect. If the router is not the IP address
owner in the VRRP group later, the configuration takes effect.
If the state of a tracked interface changes from down or removed to up, the priority of the router that
owns the interface is restored automatically.
If the state of a track entry changes from negative or invalid to positive, the priority of the router where
the track entry is configured is restored automatically.

Configuring VRRP packet attributes

Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a
virtual IPv6 address.
Configuration procedure
To configure VRRP packet attributes:
To do...
• Enter system view
•
Enter the specified interface
view
• Configure the authentication
mode and authentication key
when the VRRP groups send or
receive VRRP packets
•
Configure the time interval for
the master in the VRRP group
to send VRRP advertisement
You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP group must use the same authentication mode and
authentication key.
Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolong the time
interval to send VRRP advertisements.
Configuring different intervals for sending VRRP advertisements on the routers in a VRRP group might
cause a backup to trigger a change of its status because the backup does not receive any VRRP
