A Vlan is a broadcast domain . By default hosts in single Vlan communicates to each other . But host in different Vlans won't communicate to each other , to ensure communication between different Vlans host routing between Vlans is mandatory for Configuring routing between Vlan layer3 device is required .

What is VLAN communication?
In a LAN environment, VLANs divide broadcast domains. When a host in one VLAN must communicate with a host in another VLAN, the traffic must be routed between them. This type of routing is called inter-VLAN routing. ... With bridging, after an inbound packet is processed, the packet is associated with a VLAN.
How Inter-VLAN communication happens?
In this type of inter-VLAN routing, the interface connecting the router to the switch is usually a trunk link. The router accepts traffic that is tagged from the VLANs on the switch through the trunk link. On the router, the physical interface is divided into smaller interfaces called subinterfaces.
Can two VLANs communicate without a router?
In order to perform communication between two different vlans we require a router or mls. But it is possible to provide communication between two different vlans without using any layer 3 device. This concept is based upon tagging / untagging frames.
Is router on a stick bad?
The disadvantages to a Router on a Stick Network are: It is more complex to set up compared to other networks. Traffic between VLANs goes into the router and out of the router through the same port. The trunk is a major source of congestion.
Is VLAN and subnet the same thing?
At a high level, subnets and VLANs are analogous in that they both deal with segmenting or partitioning a portion of the network. However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network.
Why do we need VLANs?
VLANs reduce the incidence of collisions and decrease the number of network resources wasted by acting as LAN segments. Data packets sent from a workstation in a segment are transferred by a bridge or switch, which will not forward collisions but will send on broadcasts to every network devices.
What is the difference between VLAN and VPN?
Comparing VLAN Vs. VPN. VLANs are used by companies to group devices that are scattered across multiple physical locations into one broadcast domain. ... VPN is a technology that creates a virtual tunnel for secure data transmission over the Internet.
What is the difference between VLAN and inter VLAN?
Virtual LANs ( VLANS ) are networks segments on a switched LAN. Inter-VLAN routing refers to the movement of packets across the network between hosts in different network segments. ... VLANs act as separate subnet on the network.
Does a VLAN need a default gateway?
on the same vLan they should not need a default gateway, if you wanted to ping say from 192.168. 3.100 to 192.168. 5.100 you would need to set the default gateway as the core/L3 switch.
How assign IP address to VLAN?
In the Mobility Master node hierarchy, navigate to the Configuration > Interfaces > VLANs page. Select a VLAN from the VLANs table, and then select a VLAN ID under Vlan Ids. Under IPv4, select Static from the IP assignment drop-down list. Enter the IPv4 address of the VLAN interface.
Can a PC be on 2 VLANs?
Re: Making a PC a member of more than one VLAN
Now put them on a single switch, separated logically into two virtual LANs - or VLANs. If you need to communicate between the physically separate LANs, you need to link them with a router, with each LAN being connected to a different interface.
Does a VLAN have to have an IP address?
A VLAN (Virtual Local Area Network) is its own logically segregated broadcast domain. You assign networks, or subnets, just as you would with a physically separated broadcast domain. VLANs do not really have IP addresses assigned to them.
Is a VLAN Layer 2 or 3?
VLANs are data link layer (OSI layer 2) constructs, analogous to Internet Protocol (IP) subnets, which are network layer (OSI layer 3) constructs.
