	4. Example of Use
	In order to explain how this model is used, we provide the following
	example. An optical network usually has multiple transponders,
	switches (nodes) and links between them. Figure 1 shows a simple
	topology, where two physical paths interconnect two optical
	transponders.

	Figure 1. Topology example.
	In order to configure a media channel to interconnect transponders A
	and E, first of all we have to populate the flexi-grid topology YANG
	model with all elements in the network:
	1. We define the transponders A and E, including their FEC type, if
	enabled, and modulation type. We also provide node identifiers
	and addresses for the transponders, as well as interfaces
	included in the transponders. Sliceable transponders can also be
	defined if needed.
	2. We do the same for the nodes B, C and D, providing their
	identifiers, addresses and interfaces, as well as the internal
	connectivity matrix between interfaces.
	3. Then, we also define the links 1 to 5 that interconnect nodes and
	transponders, indicating which flexi-grid labels are available.
	Other information, such as the slot frequency and granularity are
	also provided.
	Next, we can configure the media channel from the information we
	have stored in the flexi-grid TED, by querying which elements are
	available, and planning the resources that have to be provided on
	each situation. Note that every element in the flexi-grid TED has a
	reference, and this is the way in which they are called in the media
	channel. We refer to
	[I-D.draft-ietf-ccamp-flexigrid-media-channel-yang] to complete
	this example.
