I don't have access to my lab, but I suspect what is happening is that R3 is
learning is this:
R3 learns the route via OSPF, and redistributes it. R8 gets the route,
installs it, and advertises it back to R3. R3 has RIP as a lower metric, so
it installs that route and advertises back to R8 with a higher hop count. R8
updates its metric, and sends to R3, which updates and sends to R8, which
updates and send to R3 etc.etc.etc.
Did you configre the R8 interface as a pt.2.pt sub-interface?
Do a show ip int xxx
Where xxx is the interface on R8 going to R3. look for ip split-horizon and
see if its disabled.
Just a rough guess of what is most likely happening..

Subject: RIP route loop
Hello all,
Here is the map of the network:
Net1 (area100) -----> R11 and R5 (two spoke Routers) ----> area0 (Frame
Relay network) ------> R3 (hub) -----> RIP (between R3 and R8 ptp).
I have a strange behaviour with Net 1 on R8. In the lab they want me to
change the AD of RIP to 95 on R3 and R8 (distance 95 under config-router).
metric of net1 on R8 increment to reach 15 and the route become unreachable.
After a couple of second, the metric start again to 1 and 2 and so on...to
unreachable.
Can you help me on this problem please ?
Regards
F.
