Object Tracking

Object Tracking supports IPv4 and IPv6, and is available on platforms: c e s

Overview

Object tracking allows you to define objects of interest, monitor their state, and report to a client when

a change in an object’s state occurs. The following tracked objects are supported:

• Link status of Layer 2 interfaces

• Routing status of Layer 3 interfaces (IPv4 and IPv6)

• Reachability of IPv4 and IPv6 routes

• Metric thresholds of IPv4 and IPv6 routes

You can configure client applications, such VRRP, to receive a notification when the state of a tracked

object changes.
