OSPF type 1 route is always preferred over a type 2 route for the same destination so we can set

metric-type 1 at Site-A RTR1 so that it is preferred over Site-B RTR2.

Note:

Routes are redistributed in OSPF as either type 1 (E1) routes or type 2 (E2) routes, with type 2 being

the default.

– A type 1 route has a metric that is the sum of the internal OSPF cost and the external redistributed

cost.

– A type 2 route has a metric equal only to the redistributed cost.

– If routes are redistributed into OSPF as type 2 then every router in the OSPF domain will see the

same cost to reach the external networks.

– If routes are redistributed into OSPF as type 1, then the cost to reach the external networks could

vary from router to router.
