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 ARST (CET – IMRSI ) Ricardo Vardasca 37 DEI .ESTG .

Summary • Router on a stick – this is an inter-VLAN routing topology that uses router sub interfaces connected to a layer 2 switch.ESTG . – 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 ARST (CET – IMRSI ) Ricardo Vardasca 38 DEI .
