Whoops... The 168,16 threw me off. I didn't read close enough to see the 168, a
s opposed to the 16.
Couldn't you use secondary addresses in the 172.16.0.0 network, or create a loo
pback with a similar mask on the RIP participating router so then?

Dan,
If you notice this is RIPv1 not RIPv2. And according to Elias, "Rip is
running only 172.168.x.x". With this in mind, when you redistribute from
OSPF(VLSM) to RIP (FLSM) across an interface which knows nothing about
172.16.x.x, then RIP will only learn about the "natural" mask. In this
case, it's class B, which is 172.16.0.0.
