In Configuration Manager 2007, the degree to which a large network is mapped at one time by Network Discovery is determined by the number of router hops that a Network Discovery run is set for. Each router hop made during the network discovery can significantly increase the amount discovered if a network is broken into multiple nodes.

To get a better idea of how router hops can affect the amount of network resources discovered, consider the following network:

Example of Router Hops in Network Discovery

A Network Discovery, running from Server 1, finds the following routers (and their attached subnets), depending on how many router hops are specified:

More detailed examples can be seen for router hops ranging from zero to four hops by clicking the following links:
