Configuring Enhanced Object Tracking
Configuring HSRP Object Tracking
Beginning in privileged EXEC mode, follow these steps to configure a standby HSRP group to track an
object and change the HSRP priority based on the object state:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
track
object-number
{
interface
interface-id
{
line-protocol
| i
p
routing} | ip route
ip-address/prefix-length
{
metric
threshold
| reachability} |
list
{
boolean
{
and
|
or
}} | {
threshold
{
weight
|
percentage
}}}
(Optional) Create a tracking list to track the configured state and enter
tracking configuration mode.
Note
Although visible in the command-line help, the
rtr
keyword is not
supported.
•
The
object-number
range is from 1 to 500.
•
Enter
interface
interface-id
to select an interface to track.
–
Enter
line-protocol
to track the interface line protocol state.
–
Enter
ip routing to
track the interface IP routing state.
•
Enter
ip route
ip-address/prefix-length
to track the state of an IP route.
–
Enter
metric threshold
to track the threshold metric. The default up
threshold is 254 and the default down threshold is 255.
–
Enter
reachability
to track if the route is reachable.
•
Enter
list
to track objects grouped in a list. Configure the list as
described on the previous pages.
–
For
boolean
, see the
“Boolean Expression” section on page 38-14
–
For
threshold weight
, see the
“Weight Threshold” section on
page 38-15
–
For
threshold percentage
, see the
“Percentage Threshold” section
on page 38-16
Note
Repeat this step for each interface to be tracked.
Step 3
exit
Return to global configuration mode.
Step 4
interface
interface-id
Enter interface configuration mode.
Step 5

]]
Create (or enable) the HSRP group by using its number and virtual IP
address.
•
(Optional)
group-number
—The group number on the interface for
which HSRP is being enabled. The range is 0 to 255; the default is 0. If
there is only one HSRP group, you do not need to enter a group number.
•
(Optional on all but one interface)
ip-address
—The virtual IP address of
the hot standby router interface. You must enter the virtual IP address for
at least one of the interfaces; it can be learned on the other interfaces.
•
(Optional)
secondary
—The IP address is a secondary hot standby router
interface. If this keyword is omitted, the configured address is the
primary IP address.
