Frame Relay End to End Keepalive

Tujuan lab kali ini adalah membuat link backup pada network Frame relay. Jika terjadi loss connection pada jalur utama frame relay, maka secara otomatis link akan memilih jalur backup untuk dilalui.

Topologi yang akan kita bahas adalah sebagai berikut :


Konfigurasi pada FRSW

interface Serial0/0
 no ip address
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay intf-type dce
 frame-relay route 102 interface Serial0/1 201
 frame-relay route 103 interface Serial0/2 301
!
interface Serial0/1
 no ip address
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay intf-type dce
 frame-relay route 201 interface Serial0/0 102
