A network engineer configures OSPFv2 on router R1. The LAN interface GigabitEthernet0/1 connects only to end-user workstations, and there are no other OSPF routers on that segment. The engineer wants R1 to advertise the GigabitEthernet0/1 subnet into OSPF but stop sending OSPF Hello packets out that interface to avoid unnecessary traffic and reduce exposure. Which configuration accomplishes this goal?
