Hello.
It seems to me that problem resides in fact that you did not specified
broadcast keyword in mapping under the BRI interface configration.
Try to use this:
"dialer map ip 172.31.25.2 name r2 broadcast"
Good luck.

Subject: RIP-OSPF Connectivity when using backup BRI
Still having problems with 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 have attached config for r2 and r5 and the the debug ip rip for both
which seem to me to say that all routes are being passed on r5 but not
processed on r2.
