Untuk mengkofigurasi Frame Relay seperti pada gambar tersebut dapat dilakukan dengan cara sebagai berikut ,
Pada Router1 tentukan interface yang akan dijadikan sebagai subinterface untuk
access multipoint dan Point-to-Point. Interface serial 2/0 akan
dijadikan sebagai subinterface nya. Lebih jelas lihat cara konfigurasi
Frame-Relay Multipoint & Point-to-Point …

Setelah konfigurasi masing-masing router selesai dilakukan, langkah selanjutnya mengkonfigurasi Cloud sebagai Frame-Relay Connection. Untuk dapat melakukan hal itu dilakukan konfigurasi manual, pada Cloud
terdapat settingan untuk Frame-Relay. Akan tetapi jangan lupa membuat
routing tabel pada masing-masing router agar transmisi packet data bisa
dilakukan. Pembuatan routing tabel dapat dilakukan secara statik routing maupun dinamic routing tergantung kondisi dan tingkat kesulitan. Untuk konfigurasi ini aku sengaja pake Routing RIP karena lebih mudah.
Kalo semua telah terkonfigurasi secara
baik, lakukan percobaan terhadap tiap-tiap router bilamana Frame-Relay
bekerja dan dapat berkomunikasi dengan router lain melalui Cloud dengan
cara “show frame-relay map” …
contoh untuk router1
R1#sh frame-relay map
Serial2/0.1 (up): point-to-point dlci, dlci 100, broadcast, status defined, active
Serial2/0.2 (up): ip 172.16.20.1 dlci 200, dynamic, broadcast, CISCO, status defined, active
Serial2/0.2 (up): ip 172.16.20.3 dlci 300, dynamic, broadcast, CISCO, status defined, active
Serial2/0.2 (up): ip 172.16.20.1 dlci 200, dynamic, broadcast, CISCO, status defined, active
Serial2/0.2 (up): ip 172.16.20.3 dlci 300, dynamic, broadcast, CISCO, status defined, active
Jelas terlihat access point-to-point dengan DLCI 100 frame-relay sedang active, begitu dengan access multipoint dengan DLCI 200 dan DLCI 300 active. show frame-relay lmi dilakukan untuk melihat status koneksi pada frame-relay
R1#sh frame-relay lmi

Pada status tersebut lebih jelas terlihat koneksi Point-to-Point dan Multipoint Frame-Relay
