Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity
to all locations in both networks. How is this accomplished without creating routing loops?
A. Use route maps on the ASBRs to allow only internal routes to be redistributed.
B. Use route maps on the ASBRs to allow internal and external routes to be redistributed.
C. Use route maps on the ASBRs to set tags for redistributed routes.
D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.
Answer: D
Explanation:
You can’t filter routes with tags unless someone tags them first…
Much easier to filter external routes when redistributing (option A).
