By default, the switch is in Layer 2 switching mode and IP routing is disabled. To use the Layer 3 
capabilities of the switch, you must enable IP routing.

Beginning in privileged EXEC mode, follow these steps to enable IP routing:

Use the no ip routing global configuration command to disable routing.

This example shows how to enable IP routing using RIP as the routing protocol:

Switch# configure terminal 

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# ip routing 

Switch(config)# router rip 

Switch(config-router)# network 10.0.0.0 

Switch(config-router)# end 

You can now set up parameters for the selected routing protocols as described in these sections:

 (optional)

The Routing Information Protocol (RIP) is an interior gateway protocol (IGP) created for use in small, 
homogeneous networks. It is a distance-vector routing protocol that uses broadcast User Datagram 
Protocol (UDP) data packets to exchange routing information. The protocol is documented in RFC 1058. 
You can find detailed information about RIP in IP Routing Fundamentals, published by Cisco Press.

RIP is the only routing protocol supported by the IP base image; other routing protocols require running 
the IP services image.

Enter global configuration mode.

ip routing 

Enable IP routing.

router ip_routing_protocol 

Specify an IP routing protocol. This step might include other 
commands, such as specifying the networks to route with the 
network (RIP) router configuration command. For information on 
specific protocols, see sections later in this chapter and the Cisco IOS 
IP Configuration Guide, Release 12.2.

The IP base image supports only RIP as a routing protocol

Return to privileged EXEC mode.
