Layer-2 protocol tunneling between a router and a switch...

Experts,
I'm confused as to how you set this situation up. If I have the following:

                           R1--Cat1--Cat2

...and I want "show cdp neighbor" on R1 to display Cat2 as a neighbor, how
would I do this?
I understand the process of setting this up between two routers, but in the
case above
the connection between Cat1 and Cat2 is a trunk. I know that on Cat1 you
disable cdp and
configure "l2protocol-tunnel cdp" under the port R1 is connected to, but
on what interface or where
do you configure things on Cat2? You can't do it on the trunk port because
the port must be
manually configured for access or dot1q-tunnel mode.?.?

Thanks,
Mod...
