Would you please provide the complete config and routing tables? You
have not included the configuration lines that give the IP addresses for
the loopback interface and the RIP interface.
BTW, unless the problem requires you to treat the loopback interface as
a subnet, a much better way to redistribute connected interfaces is as
follows:
redistribute connected subnets route-map c2o
!
route-map c2o
match interface Loopback0
You could even match several interfaces:
match interface Loopback1 Loopback2 Loopback3
