Now I have put IRB on R1 so I can test in the middle. Now, Routes are in
all 3 routers, R1 can ping R7 and R5, but R5 cannot ping through to R7. I
would guess this has to be an addressing issue. I don't now what else it
could be.
Any ideas?

It would be logical that RIP updates would work and not pings if SR/TLB was
not configured. I know you can transparently bridge Token-Ring frames, but
you cannot just Trnasparently bridge Ethernet frames into Token-Ring. You
must translate. SRT is only for going from Token-Ring to Token-Ring.
