     Hasil Traceroute dari PC A ke PC B
Disini terlihat bahwa routing diawali melalui
192.168.1.1 – 192.168.4.2 – 192.168.3.2 – 192.168.2.10 (Router 1 – Router 4 – Router 3)

Hasil Traceroute dari PC B ke PC A

Disini terlihat bahwa routing diawali melalui
192.168.2.1 – 192.168.3.1 – 192.168.4.1 – 192.168.1.10 (Router 3 – Router 4 – Router 1)

Simulasi -> A – R1 – R4 – R3 – B – R3 – R4 – R1 – A

4. Topologi no 2, A harus terkoneksi dengan B dan dipaksa routing lewat R1 - R2 - R3.
