The P4S company is deploying OSPF on a point-to-multipoint Frame Relay network. The remote sites needn??t to communicate with each other and there are a relatively small number of sites (scaling is not a concern). How to configure OSPF for this topology in order to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?
- Configure the link as OSPF no broadcast and manually configure each of the remote sites as a neighbor.
- Configure the link as OSPF broadcast and configure the hub router to always be the designated router.
- Configure the link as OSPF broadcast and configure a mesh group towards the remote routers.
- Configure the link at the hub router as OSPF point-to-multipoint and at the remote routers asOSPF point-to-point.
