Re: Router on a stick

you should not have vlan interfaces on the switch (other than the one
you choose to manage the switch by). in the global config no interface
vlanx on all vlans except #1. Then (depending on the ios version) add
the vlans you want to route using the "vlan" command or vlan database
(not in config mode for db). If you create vlan interfaces on the
switch, you are making layer 3 devices. You are trying to perform layer
three functions on the router though, so there is no need for the
interfaces on the switch. Also, only 1 vlan interface on the switch
will ever go up up. All others will be admin down. The only exception
to this is if you have a layer 3 switch and are routing in the switch
itself.
