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, Inc. All rights reserved. Cisco Public 15

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 © 2006 Cisco Systems, Inc.
