Cisco Vlan Configuration With Vlsm Implementation

Cisco VLAN Configuration Configuration with VLSM Implementation 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. cisco. Baik, mari sama-sama 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 Router Jakarta Network = 10.10.10.0 / 24 NO VLAN NAME NETWORK 1 VLAN-1 MANAGEMENT MANAGEMENT 10.0.0.0 2 VLAN-2 VLAN-2 TECHNOLOGY 10.10.10.32 3 VLAN-3 TECHNICAL SUPPORT 10.10.10.160 4 VLAN-4 VLAN-4 OPERATION 10.10.10.48
