Konfigurasi Frame Relay pada Cisco Router 805 series

Frame Relay adalah protokol WAN (Word Area Network) yang menggunakan teknologi paket switching dimana frame relay ini beropasi pada lapisan fisik dan lapisan data link pada model OSI layer.

Frame relay bekerja diantara peralatan DTE dan DCE mempergunakan Permanent Virtual Circuit (PVC), yaitu sluran virtual yang dibuat secara manual menjadikan hubungan permanent antara pengirim (DTE) dan penerima (DCE). Sebagai tanda pengenal saluran virtual tersebut digunakan Data Link Connection Identifiers (DLCI) yang berfungsi memetakan suatu nomor DLCI dengan IP address yang dipakai. Nomor pengenal DLCI yang dapat dipakai adalah 16 sampai 1007. Nomor pengenal DLCI ini hanya berlaku lokal tidak berlaku secara global. Oleh sebab itu, nomor DLCI yang sama dapat dipakai oleh jaringan lokal yang berlainan.

Dalam kasus ini, saya mencoba membuat konfigurasi jaringan Frame Relay pada Cisco 805.
