5. Hubungkan PC dengan kabel konsol untuk melakukan konfigurasi pada router dan switch.
6. Hubungkan masing-masing PC host untuk Fa0 pada / 2 antarmuka pada saklar dengan menggunakan suatu lurus-melalui kabel.

Langkah 2: Lakukan konfigurasi dasar pada Router1

Lakukan konfigurasi dasar tentang Router1 dengan nama host, interface, konsol, Telnet, dan diistimewakan password sesuai dengan diagram tabel. Gunakan RIP sebagai protokol routing, dan mengiklankan terlampir jaringan. Simpan konfigurasi.

Langkah 3: Konfigurasi router lainnya

Lakukan konfigurasi dasar yang sama pada Router2 dan Router3 dengan nama host, interface, konsol, Telnet, dan password istimewa sesuai dengan diagram tabel. Gunakan RIP sebagai protokol routing, dan mengiklankan terpasang jaringan. Simpan konfigurasi.

Langkah 4: Konfigurasi host dengan alamat IP yang tepat, subnet mask, dan gateway default

Mengkonfigurasi setiap host dengan alamat IP yang tepat, subnet mask, dan gateway default.
Dari konfigurasi yang diberikan, apa yang akan menjadi alamat IP subnetwork berikutnya tersedia di 172.30.0.0 jaringan?

Jawaban : 172.30.3.0

Jika Anda diperlukan untuk mengakomodasi LAN tambahan dengan 60 host, apa masker yang akan Anda gunakan untuk itu subnetwork?

Jawaban : / 26 (atau 255.255.255.192)

Langkah 5: Pastikan bahwa jaringan berfungsi
a. Dari setiap host, ping gateway default.

Apakah ping dari Host1 berhasil? Ya

Apakah ping dari host2 berhasil? Ya

Apakah ping dari sukses Host3? Ya

Jika jawabannya tidak untuk pertanyaan, memecahkan masalah konfigurasi router dan host

untuk menemukan kesalahan. Ping lagi sampai mereka berhasil.
b. Untuk setiap router, melihat status interface. Utama # show interface ip singkat
Branch1 # show ip interface singkat
Branch2 # show ip interface singkat

Apakah status dan protokol terdaftar sebagai up untuk semua interface yang aktif?

Jawaban : Ya.

Jika jawabannya tidak, memecahkan masalah konfigurasi router untuk menemukan kesalahan. Periksa kembali sampai status dan protokol yang up.
