By default, expanding a node marked with a plus sign adds all nodes (and their edges) that are one hop away from the node. For example, expanding an OSPF service node shows all the OSPF adjacency objects and peer OSPF service objects associated with the OSPF service node.
You can use any of the following methods to expand a node marked with a plus sign:
Select the node and then select Expand Map Element from the Map Console Map menu.
Right-click the node and then select Expand Map Element.
Select the node and click the Show neighboring nodes button.Note:
Double-clicking a node launches either a Notification Properties dialog box or a Topology Browser view for the object, depending on whether any notifications are associated with the object.
