Langkah pertama kita membuat suatu topologi jaringan seperti pada gambar di bawah ini :
Dengan rancangan IP untuk menghubungkan jaringan :
Lakukan konfigurasi pada PC sesuai IP pada tabel di atas.
Setelah itu kita akan melakukan konfigurasi pada router melalui PC yang sudah dihubungkan dengan conection console yaitu garis berwarna biru.
Setingan pada router 0 melalui PC:

Setelah selesai konfigurasi selanjutnya lakukan pengujian dengan cara melakukan ping seperti pada gambar berikut :
(Ping dari PC 0 ke Server 0)
(Ping dari Server ke PC)
Lakukan pada seluruh PC agar koneksi benar-benar saling terhubung
