I am doing IPExpert #31

I have full connectivity when all circuits are up, but if I fail the r2
serial link to r5 (at the frame switch) the Bri comes up but, my
connecivity goes away, that is routes are not be distributed between
ospf and rip. I've looked at this for sometime now. I have attached
the r5 config.
