The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols, needs authentication of users connecting to the network, and since some calls will be long distance, needs callback support. Which of the following protocols is the best choice for these remote services?

How should a router that is being used in a Frame Relay network be configured to keep split horizon issues from preventing routing updates?

Configure a separate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface.

Configure a single subinterface to establish multiple PVC connections to multiple remote router interfaces.

Configure each Frame Relay circuit as a point-to-point line to support multicast and broadcast traffic.

Configure many subinterfaces in the same subnet.
