You are deploying OSPF on a point-to-multipoint Frame Relay network. The remote sites do not need to be able to communicate with each other and there are a relatively small number of sites (scaling is not a concern).
How should you configure OSPF for this topology to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?
A . Configure the link at the hub router as OSPF point-to-multipoint and at the remote routers as OSPF point-to-point.
B . Configure the link as OSPF broadcast and configure the hub router to always be the designated router.
C . Configure the link as OSPF nonbroadcast and manually configure each of the remote sites as a neighbor.
D . Configure the link as OSPF broadcast and configure a mesh group towards the remote routers.
Answer: B
