Is it possible to configure an ip route on a layer 2 switch?

I know layer 3 switch can function as a router. But do we ever, or is it possible to, set up a route or a default gateway on a level 2 switch? If yes, how is it done?

Think about it this way, if you do not set up a default gateway on a L2 switch how would you be able to communicate with it from devices on another subnet?

For how to implement this look into the 'ip default-gateway' command.

I read somewhere that the 2960 Series has VERY LIMITED (Static Inter-VLAN Routing Only) Routing Functionality with the right IOS.

Speaking at a CCNA level, a regular switch (non-layer 3) operates on layer 2 so you can't set up IP routes because it doesn't generally accept IP commands. There are a few exceptions, however. A switch needs a default gateway - (config)#ip default-gateway - in order to communicate with a router and connect to other networks. Also, you can assign an IP address to your management VLAN so that you can telnet/SSH to a switch since Telnet/SSH operate via an IP address.
