cisco vlan configuration with vlsm implementation

Cisco VLAN Configuration with VLSM Implementation Created By : Fery Junaedi

Cukup banyak dokumentasi tentang VLAN yang bisa kita dapatkan di internet, dan ini

hanyalah salah satu dokumentasi pelengkap yang ada. Skenario yang akan kita buat kali

ini adalah membuat jaringan menggunakan perangkat cisco dengan

mengimplementasikan Network Variable Length Subnet Mask. Bagi anda yang belum

mempelajari mengenai VLSM bisa mengawali dengan materi mengenai Subnetting IP

address dan untuk tingkat lanjut ke VLSM, ini adalah materi yang cukup vital yang mesti

anda kuasai ketika anda terjun dalam dunia networking. Simulator Cisco menjadi

alternatif terbaik untuk menguji Lab Cisco yang akan kita bangun mengingat mahalnya

perangkat cisco. Baik, mari sama-sama kita bangun network VLSM pertama kita.

Skenario ini menggunakan 2 buah router dan masing-masing Network dibelakang Router

terdiri dari beberapa VLAN yang nantinya semua host bisa saling berkomunikasi antar

VLAN dan antar router. Untuk lebih mudahnya berikut tabel alokasi IP address dari

network yang kita bangun.

Tabel Alokasi IP Address VLSM
