hi,
this can be solved in the following ways.
use ip ospf demand circuit only if u are asked
to. also, configure an ospf area on the isdn circuit.
if u are asked to configure the isdn link as a
backup for a frame-relay or ethernet interface
(as in ur case) use
backup interface command on ethernet 0 interface of
r5.
i hope this helps.
