The whole scenario is based around providing resillience. Hence why the route is redistributed at both r1 and r2. In production r0 represents a eigrp domain who need to learn the routes.
The intention is that as soon r1 redistributes the static, r2 should hear it, and place it in it's route table due to better ad. Removing the static. However, you are correct, if I don't redistribute the static at r2 the failover an fail back works fine. Doesn't solve my problem however. Why is the redistribution stopping this?
