Configuring Vf Tracking - HP MSR Series Configuration Manual

Step
2. Enter Layer 3 Ethernet
subinterface view or Layer 3
aggregate subinterface view.
3. Specify an IPv6 VRRP control
VLAN.

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 configure the VFs in a VRRP group to monitor a track entry. 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 weights 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. The priority does not change with the weight. When the upstream link of the VF owner
fails, an LVF must take over as the AVF. The switchover happens when the weight of the VF owner
drops below the lower limit of failure. This requires that the reduced weight for the VF owner be
higher than 245.
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.

Remarks
N/A
By default, no IPv6 VRRP
control VLAN is specified. The
master sends IPv6 VRRP
advertisements within all
VLANs whose VLAN packets
are configured to be
terminated by the
subinterface.
