• Monitor the AVF status from the 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:
• 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
3. 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
mode and load balancing mode.
To associate Track with VRRP VF:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Associate Track with VRRP VF.
vrrp [ ipv6 ] vrid virtual-router-id
weight track track-entry-number
[ reduced weight-reduced ]
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.
The disadvantage of using static routes is that they cannot adapt to network topology changes. Faults or
topological changes in the network can make the routes unreachable, causing network breaks.
