INTER-VLAN
ROUTING.
ROUTER ON STICK

2. • Inter-vlan routing is process of forwarding network traffic from one vlan to
another.
• Router is required inter-vlan routing.
• Each vlans should be configured different IP
• The port connected to the router most be as a trunk.
• The physical interface of a routing should be should be configured sub-
interface.
• Router on a stick is a type of router configuration in a wich single physical
interface routs traffic between multiple VLANS.

3. Inter-vlan Methods
Separate physical gate way on router.
Using sub-interface.
Using layer three switch.

4. ROUTER ON A STICK
Need at-least one router.
Every VLAN has multiple gateways.
