This may be a dumb question, but i recently got a catalyst 4506 to replace my core, and I'm having trouble setting up routing for it. i issue the command ip routing, and nothing happens. the command also does not show up in the configuration. then when i do a show ip route it tells me that gateway of last resort is not set, but I've given the command ip route 0.0.0.0 0.0.0.0 x.x.x.x, and a check of the configuration shows it's in there. how do i setup routing on this device? it has a Supervisor II+ in it. currently the only thing I've got on it now is port g3/48 is connected to our old core switch. Any help would be appreciated.

I think you misunderstood.
the commands were
"ip routing" to enable ip routing on the switch
"ip route 0.0.0.0 0.0.0.0 x.x.x.x" to set the default route
now I'm not sure if the ip routing command is not showing in the config because something is wrong of if it's enabled by default on this switch, but the command "show ip route" tells me that there is no gateway of last resort setup, but as the command above states, there is.

If you just do a "ip routing" command , then its on whether you see it or not . You should be ready to go if you have the default static pointing to your next hop. You can then create vlans and route between them and anything not directly connected will be forwarded to the static route.

OK, thanks Viper for confirmation on the default routing setting. I was thinking that's the case but it's nice to get a confirmation. And you gave me the step I needed to figure it out. I was setting this up like its in place so i set the next hop to be the firewall, however the firewall is on the other side of the old core switch. right configuration had i been putting this right into production, but wrong default gateway for it's current placement.
