Building a Track Based on a List of Objects

Perform this task in the global configuration mode to create a tracked list of objects (which, in this case, are
lists of interfaces or prefixes) using a Boolean expression to determine the state of the list.
A tracked list contains one or more objects. The Boolean expression enables two types of calculations by
using either AND or OR operators. For example, when tracking two interfaces, using the AND operator, up
means that both interfaces are up, and down means that either interface is down.
Note An object must exist before it can be added to a tracked list.
The NOT operator is specified for one or more objects and negates the state of the object.
After configuring the tracked object, you must associate the interface whose state should be tracked and you
may optionally specify the number of seconds to wait before the tracking object polls the interface for its
state.
