 Monitor the master on a backup. If a fault occurs on the master, the backup working in
switchover mode will switch to the master immediately to maintain normal communication.
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.
Follow these guidelines when you associate Track with VRRP group:
 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 the status of the track entry changes from Negative to Positive or Invalid, the associated
router or VF restores its priority automatically.
 You can associate a nonexistent track entry with a VRRP group or VF. The association takes
effect only after you use the track command to create the track entry. For more information about
VRRP, see "Configuring VRRP."
To associate Track with VRRP group:
Step
Command
Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Create a VRRP group and
configure its virtual IP
address.
vrrp vrid virtual-router-id virtual-ip
virtual-address
No VRRP group is created by
default.
4. Associate a track entry with a
VRRP group.
vrrp [ ipv6 ] vrid virtual-router-id
track track-entry-number [ reduced
priority-reduced | switchover ]
No track entry is specified for a
VRRP group by default.
This command is supported when
VRRP is operating in both
standard protocol mode and load
balancing mode.
