FAQ About Vlan
Question :
- Apa yang akan terjadi jika dalam 1 perangkat switch terdapat 2 network aktif yang berbeda ?
- Apa yang dimaksud dengan vlan ?
- Apakah adapter internal network pada virtualbox termasuk vlan ?
Answer :
- Masih akan terkoneksi tetapi lama-lama akan terjadi flooding karena broadcast switch (yang pada dasarnya) hanya dapat memilki 1 broadcast domain.
- Vlan merupakan salah satu model jaringan yang bekerja pada layer 2 yang berfungsi sebagai pemisah yang membuat broadcast domain terisolasi dari LAN-lainnya. Vlan bekerja dengan menambahkan header tambahan pada paket data frame.
- Iya, karena internal adapter memilki broadcast domain yang terisolasi dari host ataupun dunia luar.
Untuk menjawab no 3 didapat dari pengertian internal adapter
sendiri yang didapatkan dari situs resmi virtualbox, yaitu :
Internal networking
This can be used to create a different kind of software-based network which is visible to selected virtual machines, but not to applications running on the host or to the outside world.

Lalu, pengertian vlan didapat dari website cisco, yaitu :
A VLAN is a group of devices on one or more LANs that are
configured to communicate as if they were attached to the same wire, when in
fact they are located on a number of different LAN segments. Because VLANs are
based on logical instead of physical connections, they are extremely
flexible.
VLANs define broadcast domains in a Layer 2 network. A
broadcast domain is the set of all devices that will receive broadcast frames
originating from any device within the set. Broadcast domains are typically
bounded by routers because routers do not forward broadcast frames. Layer 2
switches create broadcast domains based on the configuration of the switch.
Switches are multiport bridges that allow you to create multiple broadcast
domains. Each broadcast domain is like adistinct virtual bridge within a switch.
Kedua hal tersebut bersifat non fisik dan juga terisolasi.
