• Point-to-Point
• Point-to-Multipoint

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

• In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.
• In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30
