Konfigurasi Dasar Border Gateway Protocol (BGP)

Pada skenario kali ini kita akan melakukan konfigurasi BGP, masih mengikuti topologi Tutorial 11 sebelumnya bahwa sebuah jaringan terdiri dari 3 (tiga) LAN yang memiliki Network ID yang berbeda-beda. Setiap LAN tersebut dipisahkan dengan router. Router yang digunakan seri 1941 dan Switch yang digunakan seri 2960.

Tugas anda adalah sbb:

  • Hapus semua protokol IGP (Interior Gateway Routing Protocol).
  • Melakukan konfigurasi BGP di semua router.

KONFIGURASI
