- Frame Relay juga memiliki kemampuan multilink yaitu membundle beberapa link serial menjadi satu
- Bisa juga menambahkan authentikasi multilink frame relay
Metode Lab :
- Gunakan dua kabel serial pada masing-masing link
- Konfigurasikan Multilink
- Konfigurasikan Authentikasi

Verifikasi Lab
Terlihat diatas, ip tersebut masih dapat diping meskipun interface S0/0 pada R1 telah down.
Pada PPP, username harus menggunakan hostname lawannya. Jika diinginkan menggunakan username yang lain, konfigurasinya seperti berikut :
R1(ocnfigif)#username BOGOR password 0 RAHASIA
R1(ocnfigif)#interface Virtual-Template1
R1(ocnfigif)# ppp chap hostname JAKARTA
R2(ocnfigif)#username JAKARTA password 0 RAHASIA
R2(ocnfigif)#interface Virtual-Template1
R2(ocnfigif)# ppp chap hostname BOGOR
