Chapter 40 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
Step 1 configure terminal
Step 2 track object-number {interface
interface-id {line-protocol | ip
routing} | ip route
ip-address/prefix-length {metric
threshold | reachability} | list
{boolean {and | or}} | {threshold
{weight | percentage}}}
Step 3 exit
Step 4 interface interface-id
Step 5
standby [group-number] ip
[ip-address [secondary]]
OL-9639-07
Purpose
Enter global configuration mode.
(Optional) Create a tracking list to track the configured state and enter
tracking configuration mode.
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 or 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 or enter
•
reachability to track if the route is reachable.
The default up threshold is 254 and the default down threshold is 255.
Enter list to track objects grouped in a list. Configure the list as
•
described on the previous pages.
For boolean, see the
–
Expression" section on page 40-4
For threshold weight, see the
–
Weight Threshold" section on page 40-5
For threshold percentage, see the
–
a Percentage Threshold" section on page 40-6
Repeat this step for each interface to be tracked.
Note
Return to global configuration mode.
Enter interface configuration mode.
Create (or enable) the HSRP group by using its number and virtual IP
address.
• (Optional) group-number—Enter a 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—Specify 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—Specify that the IP address is a secondary hot
•
standby router interface. If this keyword is omitted, the configured
address is the primary IP address.
