Types of Virtual LAN (VLAN) - GeeksforGeeks (2024)

Virtual LAN (VLAN)

Virtual LAN (VLAN) is a concept in which we can divide the devices logically on layer 2 (data link layer). Generally, layer 3 devices divide the broadcast domain but the broadcast domain can be divided by switches using the concept of VLAN. A broadcast domain is a network segment in which if a device broadcast a packet then all the devices in the s

Difference Between Default VLAN and Native VLAN

Understanding their differences helps in configuring and troubleshooting VLANs correctly in a network surrounding. What is Default VLAN?In Default VLAN all switch ports turn into a member of the default VLAN just after th

Difference between LAN and VLAN

LANs and VLANs are both ways to connect computers in a network, but they work a bit differently. A LAN, or Local Area Network, is like a group of computers in one place, like an office or home. These computers are connected by cables or Wi-Fi and can share information and resources easily. It's like having all your friends in the same room, talking

Types of area networks - LAN, MAN and WAN

The Network allows computers to connect and communicate with different computers via any medium. LAN, MAN, and WAN are the three major types of networks designed to operate over the area they cover. There are some similarities and dissimilarities between them. One of the major differences is the geographical area they cover, i.e. LAN covers the sma

Inter VLAN Routing by Layer 3 Switch

Prerequisite - Access and trunk ports Normally, Routers are used to divide the broadcast domain and switches (at layer 2) Operate in a single broadcast domain but Switches can also divide the broadcast domain by using the concept of VLAN (Virtual LAN). VLAN is the logical grouping of devices in the same or different broadcast domains. By default, a

VLAN Trunking Protocol (VTP)

To carry traffic of a VLAN, it must be first configured on the switch. Suppose, if the user wants to send a frame from source to destination and the shortest path between them contains 1000 switches. To process a frame of any VLAN, VLANs should be configured first so, have to configure the same VLANs on all the 1000 switches manually. It will not b

Private VLAN

Prerequisite - Virtual LAN (VLAN) Virtual LAN (VLAN) is used to break a broadcast domain into smaller domain at layer 2. Only (all) hosts belonging to same VLAN are able to communicate with each other while communicating with other VLAN hosts, Inter Vlan routing is done. But in same VLAN, if we want some hosts should not be able to communicate with
