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

Running a topology-only Network Discovery from Server 1 with two router hops will discover the following:
- Router 1 and subnet 10.1.10.0
(found with zero hops).
- Subnets 10.1.20.0 and 10.1.30.0,
subnet A, and Router 2 (found on the first hop).
- Subnets B and C, and Router 3 (found on
the second hop).
- Subnets D and E, and Router 4 (found on
the third hop).
- Subnet F (found on the fourth hop).
