Step Task Command Syntax Command Mode
1 Configure object tracking on the
reachability of an IPv4 or IPv6 route.
track object-id
{ip route ip-address/prefix-len |
ipv6 route ipv6-address/prefix-len}
reachability [
vrf vrf-name]
Valid object IDs are from 1 to 65535.
Enter an IPv4 address in dotted decimal
format; valid IPv4 prefix lengths are from /
0 to /32.
Enter an IPv6 address in X:X:X:X::X
format; valid IPv6 prefix lengths are from /
0 to /128.
CONFIGURATION
2 (Optional) Configure the time delay
used before communicating a change
in the status of a tracked route.
delay {[up seconds] [down seconds]}
Valid delay times are from 0 to 180
seconds. Default: 0.
OBJECT TRACKING

with a text description.
description text

4 (Optional) Display the tracking
configuration and the tracked object’s
status.
