The Network Analysis Extension manages the feature layers for the current network. Only those feature layers added to the Extension are considered when the user interacts with the map, such as adding flags and barriers using the Flag and Barrier tools, displaying the flow arrows, and drawing the results of a trace task.

The FeatureLayer propety returns a feature layer for the current network that has been added to the Network Analysis Extension using the AddLayer method.

In general, it is not necessary to manually add and drop layers from the Network Analysis Extension, as the Extension automatically performs this when a feature layer from the current network is added or deleted from the focus map of the document.
