OK, no problem. I'll accept that. My version of IOS will not allow packets to be sent out the interface unless the primary interface is in the routing process, which violates the requirements given.
Can anyone think of any other ways to do this? Suppose you aren't allowed to use subinterfaces anywhere.
Look at the original requirements given. Hint: I didn't say you could not use tunnels, I just said you can't use the configuration posted. Anytime you see something out of the ordinary like this, something should click in your head that perhaps theres a way to do it similar to, but not exactly, to the prohibited statements...
Good luck again!
Ken

As you can see, R1 is sourcing both loopback networks via the seconday
address.
