OSPF/RIP mutual redistribution with 2 border routers

> I am confused about the issues involved with redistributing both ways between
 two different protocols. I tried to set up Caslow's example on page 421 "Redis
tributing and Admin Distance", but I can't create a routing loop (prior to addi
ng any distribution lists).

the OSPF database has a route to the OSPF-11 router), hence breaking the routin
g loop. I would think that OSPF's lower admin distance would cause the loop as
the author states. Does OSPF have a built-in defense against this creating rout
ing loops?
