The inter-vlan routing is a proporties of in vlan routing. there are some point about inter vlan routing.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) )
Consider, this, as the network administrator, one of your tasks is to create and assign different users to VLANs in your network, you have three main departments which should be logically segmented using VLANs, VLAN 10 – FINANCE, VLAN 20 – SALES and VLAN 30 – HR.
The use of VLANs means that users would not be able to communicate across departments, i.e. a user in FINANCE, would not be able to send a message to a user in SALES since they are on different broadcast domains.
In many enterprises, you will find that information sharing across departments is a requirement, therefore, the question begs, how do you make users in the SALES and FINANCE department communicate, yet they are on different VLANS?
