Re: OSPF ABR behavior in redistribute static route
A couple of things must be stressed in this scenario.
First, a router in OSPF that performs redistribution is by definition an ASBR, not an ABR.
Second, the redistribution is performed over object in the routing table. Only objects already present in the routing table can be redistributed into other routing protocols. In your example, if a static route is redistributed into the OSPF, it must first be present in the routing table and it must remain there so that it can be redistributed indefinitely. If the route stops being static and becomes a different type, say, OSPF-learned, then the command redistribute static no longer applies to it because the route is not static anymore.
Third, you have a race condition scenario in your network. One of the routers learns about the redistributed route from the other, and because OSPF-learned routes have lower AD than your static route AD of 200, it will replace the static route in that router's routing table. The network will in this case converge on one router redistributing the static route into OSPF and the second router simply learning that route via OSPF. A worse-case scenario is that both routers will redistribute this route into OSPF, advertise it simultaneosly, learn about it from each other simultaneously, replace their static route in their routing tables with the OSPF-learned route (pointing to each other, creating a temporary routing loop), then removing that route from the routing table because none of the routers has the source static route anymore, thus placing back the static route - and doing this all over again in possibly neverending cycle.
