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
interfaces are up, and down means that
interface is down.
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.
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.
