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 routing Requires multiple router interfaces that are each connected to separate VLANs © 2006 Cisco Systems.

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 © 2006 Cisco Systems.
