Configuring Vf Tracking - HP 6125G Configuration Manual

Configuration procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, determine which
router in the VRRP group serves as the master.
To configure router priority, preemptive mode and interface tracking:
Step
1. Enter system view.
2. Enter the specified interface
view.
3. Configure the priority of the
router in the VRRP group.
4. Configure the router in the
VRRP group to operate in
preemptive mode and
configure preemption delay of
the VRRP group.
5. Configure the interface to be
tracked.
6. Configure VRRP to track a
specified track entry.

Configuring VF tracking

Configuration guidelines
You can configure the VF tracking function when VRRP is operating in either standard protocol
•
mode or load balancing mode. However, the VF tracking function is effective only when VRRP is
operating in load balancing mode.
By default, the weight of a VF is 255, and its lower limit of failure is 10.
•
If the weight of a VF owner is higher than or equal to the lower limit of failure, the priority of the VF
•
owner is always 255 and does not change with the weight value. Therefore, if an uplink fails,
another VF takes over the VF owner's work and becomes the AVF only when the weight of the VF
owner decreases by a properly specified value and becomes lower than the lower limit of failure.
In other words, the weight of the VF owner decreases by more than 245.
Configuration prerequisites
Before you configure the VF tracking function, create a VRRP group and configure a virtual IPv6 address
for it.
Configuration procedure
VRRP operates in load balancing mode. Assume that you have configured the VF tracking function to
monitor a track entry and specified the value by which the weight decreases. When the status of the track
entry becomes negative, the weight values of all VFs on the router decrease by the specified value. When
