How does a router route between VLANs?
The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.
CAN Layer 2 switches do inter-VLAN routing?
SVI (Switch Virtual Interface) This configuration might look familiar if you worked with layer 2 switches before. On a layer 2 switch like the Cisco Catalyst 2950/2960 we also have a SVI but you can only use it for remote management.
Can VLAN talk to each other?
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 .
Is the voice vlan the same as the data VLAN?
The Voice VLAN is also known as the Auxiliary VLAN (AUX VLAN) The computer will be in a data VLAN, the IP phone will be in the voice VLAN. It will look like this: Behind the scenes, we have a trunk between our switch and IP phone.
What are the options for routing between VLANs?
There are three options available in order to enable routing between the VLANs: Router with a Separate Physical Interface in each VLAN; Router with a Sub-Interface in each VLAN; Utilizing a Layer 3 Switch; The remainder of this article will explore these three options and their configuration. Router with Separate Physical Interfaces
How does the IP phone know which VLANs to use?
We configure the interface in access mode and use VLAN 100 for the computer. The switchport voice vlan command tells the switch to use VLAN 101 as the voice VLAN. We configured the switch but how does the IP phone know which VLANs to use? Cisco IP phones use CDP (Cisco Discovery Protocol) for this.
How is a VLAN related to a broadcast domain?
A VLAN can be thought of as a broadcast domain that exists within a defined set of switches. A VLAN consists of a number of end systems, either hosts or network equipment (such as bridges and routers), connected by a single bridging domain.
