Refer to the exhibit.
Both Switch-1 and Switch-2 redistribute RIP routes into OSPF. The network administrator wants routers in Area 1 to receive the redistributed routes from Switch-1 but not from Switch-2.
What should the administrator do to achieve this goal?
A. Configure Area 1 as a stub area, with no summaries on Switch-2.
B. Configure Area 1 as a stub area, and import the routes with a low metric on Switch-2.
C. Configure Area 1 as a Not So Stubby Area (NSSA) on all routing devices in Area 1.
D. Configure a subnet range for Area 1 on Switch-2, and set the no-advertise option.
it should be B, isnt it?
