Routable vs. Non-routable

Additionally, protocols may be routable or non-routable. To understand what this means, recall the description of a router from the chapter on network devices: a router connects multiple networks to create what is called an internetwork. A routable protocol is capable of being passed from network to network. A non-routable protocol is restricted to use only on its LAN, and does not get passed to other networks by a routing protocols running on a router (at OSI layer 3).

Generally, non-routable protocols contain less protocol overhead and are thus more efficient than routable protocols. The trade-off is that they can only be used within a LAN environment.
