Tunneling itu apa sih ? Tunneling adalah teknik mengenkapsulasi seluruh paket data dari format protokol yang lain. Dengan kata lain, paket data asli akan ditambahkan header dari tunneling protokol tersebut. Hasil enkapsulasi tersebut kemudian akan dikirim melalui infrastruktur jaringan menuju node tujuan.


Kali ini saya mencoba membuat simulasi tunneling secara manual. Topologi perencanaan manual tunneling ini  :

Topology

Yang dibutuhkan untuk implementasi:

1. 1 buah Komputer/Laptop
2. Software GNS3, dapat didownload disini
3. IOS cisco c3725-adventerprisek9-mz.124-18.bin, dapat didownload disini
4. Virtual PC, dapat didownload disini
