The auto link function refers to automatically draw links between devices or sites on a map. For example, when you draw devices on a map, the links between the connected devices are automatically drawn based on IPv4 Layer 3 topology by default. You can change the default topology type by Customizing Auto Link Options.
To change the topology type for the auto link on your map:
1.Right-click the blank area on the map and select Auto Link.
2.Select one topology type among all available options.
