Layer 3 routing without routing protocols

[mahesh18]

                   Hi Everyone,

Need to know about layer 3 routing without using routing protocols.

Our Client has Network where they are doing Layer 3 routing with vlans without using routing protocols.

Never heard of this before.

Core switch runs routing protocol and it has Vlan configured which do the routing with all the distribution switches.

They have no VTP configured on distribution switches.VTP is turned off on distribution switches

Is there way where we can turn off VTP on cisco switches??

Users connect to distribution switches and they have different vlan configured for various groups on distribution switches

Connection to core is by vlan which is routing vlan and default gateway configured on distribution switches.

Need to know is this Network type layer 3 by  vlan??

Need to know more info how this type of network  works?

Any reference to reading material ???

Thanks

MAhesh
