Configuring Vf Tracking; Disabling An Ipv4 Vrrp Group - HP 6125XLG Configuration Manual

Configuring VF tracking

You can configure VF tracking in both standard mode and load balancing mode, but the function takes
effect only in load balancing mode.
In load balancing mode, you can establish the collaboration between the VFs and NQA or BFD through
the tracking function. When the state of the track entry transits to Negative, the weights of all VFs in the
VRRP group on the router decrease by a specific value. When the state of the track entry transits to
Positive or NotReady, the original weight values of the VFs restore.
Configuration guidelines
• By default, the weight of a VF is 255, and its lower limit of failure is 10.
When the weight of a VF owner is higher than or equal to the lower limit of failure, its priority is
•
always 255 and does not change with the weight. To guarantee that an LVF can take over the VF
owner as the AVF when the upstream link of the VF owner fails, the reduced weight for the VF owner
must be higher than 245 so the weight of the VF owner can drop below the lower limit of failure.
Configuration procedure
To configure VF tracking:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the VFs in a VRRP
group to monitor a track entry
and configure the reduced
weight.

Disabling an IPv4 VRRP group

You can temporarily disable an IPv4 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 the VRRP group is disabled. Your changes take effect when you enable the VRRP group
again.
To disable an IPv4 VRRP group:
Step
1. Enter system view.
2. Enter interface view.
3. Disable a VRRP group.
