2. Routing Static.doc

PRAKTEK 2 Tujuan : Mahasiswa dapat mengerti dan melakukan konfigurasi routing static pada simulasi jaringan yang dibuat. ROUTING STATIC

Routing Static  Masukan atau daftarkan network address yang tidak terubung secara langsung (directly connected). Administrative distance (tingkat kepercayaan network address dalam routing tabel) adalah 1. Dalam routing static harus ditentukan arah paket (packet flow) agar routing dapat konvergence (valid). Dalam praktek ini arah paket routing adalah searah jarum jam.  Berikut step – step konfigurasi setiap roter : R1 : R1>en R1#conf t Enter configuration commands, one per line.

Praktek : 1. Buatlah desain topologi jaringan seperti diatas. 2. Lakukan konfigurasi seperti langkah-langkah diatas untuk setiap router. 3. Lakukan pengalamatan pada setiap PC 4. Lihatlah tabel routing setiap router. Bagaimana hasilnya? 5. Lakukan Ping antara setiap PC. Bagaimana hasilnya? Tugas : 1. Apa itu routing static? 2. Mengapa pada routing static yang didaftarkan adalah alamat yang tidak terhubung secara langsung? 3. Tambahkan satu buah router dan PC pada topologi diatas (R4) 4. Tambahkan sebuah Switch antara setiap router dan PC 5. Lakukan konfigurasi pada router R4 dengan alamat IP 10.1.0.12 dan pada PC 192.168.4.0 6. Daftarkan alamat router R4 dan PCnya pada router R2. 7. Ujilah apakah koneksi anatara R2 dan R4 dapat berjalan. 8. Jelaskan dan Praktekkan di depan kelas pada pertemuan selanjutnya (Kel. Febby dan Ferika). 9. Berikan kesimpulan dari praktek yang baru saja anda lakukan.
