Setup Guide

The refresh interval range is from 0 to 60 seconds. The default is 60 seconds.
Examples of IPv4 and IPv6 Tracking Route Reachability
The following example shows how to change the refresh interval for tracking the reachability of the next-hop:
DellEMC#configure
DellEMC(conf)#track reachability refresh 20
For example, consider that the next-hop address is changed and the track reachability is checked after the set refresh interval (20
seconds). If the reachability to the next-hop address is failed, the system displays the following log stating that the track object state is
changed from UP to DOWN.
Sep 28 11:08:57 %STKUNIT1-M:CP %OTM-6-STATE: Object 2 state transition from Up to Down.
Tracking a Metric Threshold
Use the following commands to congure object tracking on the metric threshold of an IPv4 or IPv6 route.
To remove object tracking, use the no track object-id command.
1 (Optional) Recongure the default resolution value used by the specied protocol to scale the metric for IPv4 or IPv6 routes.
CONFIGURATION mode
track resolution {ip route | ipv6 route} {isis resolution-value | ospf resolution-value}
The range of resolution values is:
• ISIS routes - 1 to 1000. The default is 1.
• OSPF routes - 1 to 1592. The efault is 1.
2 Congure object tracking on the metric of an IPv4 or IPv6 route.
CONFIGURATION mode
track object-id {ip route ip-address/prefix-len | ipv6 route ipv6-address/prefix-len} metric
threshold [vrf vrf-name]
Valid object IDs are from 1 to 500.
Enter an IPv4 address in dotted decimal format. Valid IPv4 prex lengths are from /0 to /32.
Enter an IPv6 address in X:X:X:X::X format. Valid IPv6 prex lengths are from /0 to /128.
(Optional) E-Series only: For an IPv4 route, you can enter a VRF name.
3 (Optional) Congure the time delay used before communicating a change in the UP and/or DOWN status of a tracked route.
OBJECT TRACKING mode
delay {[up seconds] [down seconds]}
Valid delay times are from 0 to 180 seconds.
The default is 0.
4 (Optional) Identify the tracked object with a text description.
OBJECT TRACKING mode
description text
The text string can be up to 80 characters.
5 (Optional) Congure the metric threshold for the UP and/or DOWN routing status to be tracked for the specied route.
OBJECT TRACKING mode
