Elements in the control bar include, from left to right:
- Map: Displays the currently selected region.
- To find a resource by name, enter the name in the search window. When a match is found and selected, the view will zoom in to that resource.
Refresh: updates the view in the main map window. The view is refreshed every three minutes, but if a change was made since the last refresh you can choose to manually trigger a refresh of the diagram.
Export Map Data: Exports a zip file containing a high resolution .png map of the resources in the current region and compartment, and a .pdf file containing a lower resolution version of the map plus resource data (such as route tables). This PDF only includes the resource information for the elements seen in the map at the time of export.
Filter: Allows you to turn on and off the filters used in the current view. 
Legend: Displays the symbols used in the map and their meaning.

Resources in your external on-premises network are shown on the left side of the canvas and are separated from elements in the Oracle Cloud by a dashed line.
The zoom controls are in the lower right corner of the diagram canvas, and you can click the canvas and hold as you move to pan up, down, left, or right. You can also double-click to zoom in.
You can dynamically rearrange resources on the map by dragging them. Be aware these changes are temporary and do not persist if the map is refreshed.
Routes that are enabled between resources are shown on the lines connecting the resources. Routes can be one way, but are most often two-way connections.
Some resources are displayed with both a name and an associated CIDR block. When more than one CIDR block is associated with a resource, a +1 or +2 is added as appropriate (up to +99). The additional CIDR blocks are listed in the details screen for the resource.
Any connected elements you do not have the needed permissions to view are shown with a tag:
. Only the OCID is visible for that resource.

Click any resource on the map (the resource changes color to indicate the selection) to view basic information for that item in the right-hand column. The details presented vary depending on the component you selected.
For some components, you can also click Open Additional Details to open a details screen for that component. These details are read-only summaries of the basic components for that resource. Links to that resource's details page are provided in case you want to make edits.
You can click on the link icon
on a line connecting a DRGv2 and another resource. This selects the associated DRG attachment and you can can observe its properties in the details screen. When you select the DRG attachment the routes within the DRG between the selected DRG attachment and other DRG attachments. These routes are determined by the routing table associated with the DRG attachment. If you click on one of these internal connections, any additional CIDR blocks are listed in the details screen for the connection. This capability is only available for connections that involve a DRG v2.

Use the networking-topology get command and required parameters to get a virtual network topology for the current region and specified compartment:
oci network networking-topology get --compartment-id compartment_OCID ... [OPTIONS]For a complete list of flags and variable options for CLI commands, see the CLI Command Reference.
Run the GetNetworkingTopology operation to get a virtual network topology for the current region and specified compartment.
The response body will contain a single NetworkingTopology resource, which contains the following resources showing relationships between entities in the network:
