Can someone explain to me exactly why "ip routing" needs to be enabled on a switch in order to perform interVLAN routing?
ip routing command and InterVLAN routing

some multilayer switches don't have layer 3 routing enabled by default. in other words, out of the box, they are just layer 2 switches. the "ip routing" command" enables layer 3 routing.
Switches were traditionally a L2 device, and many people still buy a switch for that role. They expect to use their age old scripts with ip default-gateway in to just work on the new switch, so IP routing is disabled.
