When VRRP is operating in load balancing mode, associate the track module with the VRRP Virtual Forwarder (VF) to implement the following functions: • Change the priority of the active VF (AVF) according to its uplink state. When the uplink of the AVF fails, the track entry changes to Negative state and the weight of the AVF decreases by a specific value so that the VF with a higher priority becomes the new AVF to forward packets. • Monitor the AVF status from the listening VF (LVF), which refers to the VF in listening state. When the AVF fails, the LVF that is operating in switchover mode becomes the new AVF to ensure continuous forwarding. VRRP tracking is not valid on an IP address owner. An IP address owner refers to a router when the IP address of the virtual router is the IP address of an interface on the router in the VRRP group.

When VRRP is operating in load balancing mode, associate the track module with the VRRP Virtual
Forwarder (VF) to implement the following functions:
•
Change the priority of the active VF (AVF) according to its uplink state. When the uplink of the AVF
fails, the track entry changes to Negative state and the weight of the AVF decreases by a specific
value so that the VF with a higher priority becomes the new AVF to forward packets.
•
Monitor the AVF status from the listening VF (LVF), which refers to the VF in listening state. When the
AVF fails, the LVF that is operating in switchover mode becomes the new AVF to ensure continuous
forwarding.
VRRP tracking is not valid on an IP address owner. An IP address owner refers to a router when the IP
address of the virtual router is the IP address of an interface on the router in the VRRP group.
