Summary Inter-VLAN routing is the process of routing information

between VLANs

Inter-VLAN routing requires the use of a router or a layer 3 switch

Traditional inter-VLAN routingRequires multiple router interfaces that are each connected to separate VLANs

Summary

Router on a stick this is an inter-VLAN routing topology that uses router sub interfaces connected to a layer 2 switch.

Each Subinterface must be configured with:

An IP address

Associated VLAN number

Configuration of inter VLAN routing–Configure switch ports connected to router with correct VLAN

–Configure each router subinterface with the correct IP address & VLAN ID

Verify configuration on switch and router
