I'm very sure, I am not confused. I've been doing this for more than 4 years.
Don't confuse yourself with the term non-routable protocols and non-routable
addresses.
Most IP managers term RFC1918 as private-addresses, reserved-address or
non-routable addressess.
Non-Routable addresses
10.0.0.0-10.255.255.255/8
172.16.0.0.-172.31.255.255/12
192.168.0.0-192.168.255.255/16
Non-Routable Protocol
Netbeui, DLC (since this is layer two but I 'm prettry sure that these two
protocols can be enveloped/encapsulated/tunneled)
Routable or routed Protocols
ip, ipx and so on
Routing Protocols
igrp, bgp, ospf, rip and so on
But these non routable addresses are really routable. The IP committee just termed
it as non-routable addresses because they cannot be routed over public WAN. We use
public-ip addresses on the Internet.
Regarding the term routed and routing, please take a look at

I hope this clarifies everything.
