• Monitor the master on a backup. If a fault occurs on the master, the backup operating 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 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 user-specified value so that the VF with a higher priority becomes the new AVF to forward packets. Follow these guidelines when you associate Track with VRRP: • 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 NotReady, 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. 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 No track entry is specified for a VRRP group by default. 3. Associate a track entry with a vrrp [ ipv6 ] vrid virtual-router-id VRRP group. track track-entry-number [ reduced priority-reduced | switchover ] This command is supported when VRRP is operating in both standard protocol mode and load balancing mode. To associate Track with VRRP VF: Step 1. Enter system view. 2. Enter interface view. Command system-view interface interface-type interface-number vrrp [ ipv6 ] vrid virtual-router-id 3. Associate Track with VRRP VF. weight track track-entry-number [ reduced weight-reduced ] Remarks N/A N/A By default, no track entry is specified for a VF. This command is configurable when VRRP is operating in standard mode or load balancing mode. However, this command takes effect only when VRRP is operating in load balancing mode. Associating Track with static routing A static route is a manually configured route. With a static route configured, packets to the specified destination are forwarded through the path specified by the administrator. For more information about static route configuration, see Layer 3-IP Routing Configuration Guide. 99

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 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
user-specified value so that the VF with a higher priority becomes the new AVF to forward packets.
Follow these guidelines when you associate Track with VRRP:
•
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 NotReady, 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.

Associating Track with static routing
A static route is a manually configured route. With a static route configured, packets to the specified
destination are forwarded through the path specified by the administrator. For more information about
