                                          An engineer is designing an EIGRP network for a small branch site where there is only one Layer
                                          3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN.

                                          • A. Advertise the local LAN using the network command and the passive-interface feature
                                          • B. Redistribute the local LAN network using the redistribute connected command
                                          • C. Use a static default route for this site instead of EIGRP
                                          • D. Advertise the local LAN subnet as a stub network
