How to configure Router on a Stick

Hi Regina,

The configuration on the Cisco switch is pretty straightforward. The interface connected to the router has to be a trunk:

interface fa0/24
description LINK_TO_ROUTER
switchport mode trunk

And the interfaces that connect to the host are regular access ports:

interface fa0/1

description HOST_IN_VLAN_10
switchport mode access
switchport access vlan 10

You don’t need to use VLAN SVIs…a layer 2 switch uses the SVI only for management purposes. A layer 3 switch uses a SVI per VLAN which hosts can use as default gateway (in that case you don’t need a router on a stick anymore).
